A faster, more accurate way to explore innovation data—now available in Cypris.
For innovation teams, speed and accuracy aren’t optional—they’re critical. You need to quickly find all relevant documents, slice and dice datasets however you want, and trust that the results are complete and representative. With this in mind, we’ve upgraded how semantic search works inside Cypris.
Today, we’re launching an upgraded search infrastructure that gives users access to full, exact result sets—unlocking more powerful analysis, faster iteration, and deterministic filtering and charting.
Unlike traditional semantic or vector search engines—which make it difficult to count, filter, or chart large sets of matched documents—our new approach prioritizes transparency and performance while preserving semantic relevance.
Why we moved away from vector search
Our original implementation relied on semantic and vector search to capture the “meaning” behind user queries. But as our platform evolved, it became clear that these systems weren’t well-suited for our core use cases.
Users needed:
- Deterministic filtering (e.g., "how many results match this atom?")
- Transparent, complete result sets to power charts and dashboards
- Fast, repeatable queries that don’t change subtly over time
Modern vector search systems don’t easily support this level of transparency. They return approximate matches and abstract similarity scores, often making it hard to understand why a document was returned—or whether it’s the full picture.
So we made a decision: move away from vector search and lean into what traditional search engines do best.
A return to boolean and lexical search—with a twist
We rebuilt our search infrastructure on top of Elasticsearch’s powerful boolean and lexical search capabilities. This shift brings major advantages:
- Faster query speeds that dramatically improve iteration time
- Deterministic filtering and counts, so every chart is grounded in the full dataset
- Predictable, explainable results that users can trust
But we didn’t stop there.
To preserve the benefits of semantic understanding, we’ve rethought where that intelligence should live—not at query time, but at data ingestion.
Capturing semantic meaning at ingest time
Instead of computing document-query similarity during search, we enrich documents at the time of ingestion. Here’s how:
- Synonym expansion: We find related words and concepts not explicitly mentioned in the document and add them as fields, enabling semantic-style recall via lexical search.
- Stemming: Both queries and documents are reduced to their root forms, allowing consistent matches (e.g., “running” and “run”).
The result? You get the same functionality—semantically relevant results—without the opacity or latency tradeoffs of vector search.
What’s next: Reranking for even better relevance
We’re not done. Coming soon to Cypris is a reranking layer that boosts the most relevant results to the top of the list using lightweight vector techniques.
Here’s how it works:
- A standard lexical search retrieves the full result set.
- We take the top N results and rerank them using vector similarity, powered by Elasticsearch’s new hybrid scoring capabilities.
- You get faster queries with even better relevance—without compromising on counts or transparency.
This layered approach gives us the best of both worlds: precise filtering and fast queries, plus smarter ordering of results where it matters most.
We’re excited to bring this upgrade to our users, and we’re already seeing teams iterate faster and uncover insights more confidently. This is a foundational shift—and just the beginning of what’s to come.

An ontology is a formal, machine-readable specification of the concepts in a domain and the relationships among them. The term has a precise meaning in knowledge representation: an explicit specification of a conceptualization,¹ that is, a defined vocabulary of entity types, attributes, and relations, together with constraints on how they may be combined. This distinguishes an ontology from a flat taxonomy, which only arranges terms hierarchically; an ontology also encodes non-hierarchical relations, such as a material being used in a process or a method being applied to a claim. In R&D and patent intelligence, the ontology defines the domain schema: the technologies, materials, methods, claims, organizations, and research areas that matter, and the relationship types that connect them.²
A knowledge graph instantiates that schema over real data. It represents information as a graph of nodes and typed edges, commonly expressed as subject-predicate-object triples, linking specific patents, scientific papers, assignees, inventors, technologies, and materials as connected entities rather than isolated documents. Building the graph requires several engineering steps that determine its quality: named-entity recognition and relation extraction to convert unstructured patent and paper text into triples; entity resolution to normalize the many surface forms of an organization, inventor, or compound to a single canonical node; and provenance tracking so every assertion in the graph traces back to the source document that supports it. The result is a structure that can be queried declaratively, for example with a graph query language, and that supports multi-hop traversal, so a question can follow chains of relationships rather than matching a single string.
This structure matters because patents and scientific literature become intelligence only when their relationships are made explicit. A ranked list of relevant documents does not state how a technology area is organized, which organizations are active, how research connects to patents, or where the graph is sparse. An ontology-backed knowledge graph makes those relationships first-class and queryable. A team can ask how two technologies relate, which body of research underpins a patent cluster, which assignees co-file in an area, or where a domain is unclaimed, and receive an answer computed over structured connections rather than assembled by reading.
The 2026 relevance is that structured knowledge is the most reliable way to ground generative AI. Large language models produce fluent output but can assert unsupported claims when they generate from parametric memory over unstructured text. Retrieval-augmented generation (RAG), which conditions a model's output on retrieved external evidence, was introduced to address this and improves factual accuracy on knowledge-intensive tasks.³,⁴ Graph retrieval-augmented generation (GraphRAG) extends RAG by retrieving connected subgraphs rather than isolated passages, so the model reasons over entities and their relationships and can answer questions that require traversing multiple hops.⁵,⁶ Grounding a system on an ontology-backed knowledge graph constrains its outputs to real, connected entities, which is essential for patent and R&D work where every conclusion must trace to actual patents and papers, and where retrieval quality directly governs the reliability of downstream generation.⁷ It is also what makes agentic workflows dependable: an agent reasoning over a structured, provenance-tracked graph produces results a team can verify against sources.
What an ontology and knowledge graph add to patent intelligence
Multi-hop reasoning over relationships. A knowledge graph answers relational and multi-hop questions, such as how two technologies connect through shared materials or which research a patent cluster builds on, rather than only returning documents that match a query string.
Concept-organized semantic search. Dense semantic retrieval returns conceptually relevant documents; the ontology organizes that retrieval within a domain schema, improving both recall and the interpretability of results by grouping them under defined concepts.
White space analysis. White space analysis depends on clustering activity by concept to expose genuine gaps. Clustering patents and papers over the ontology's relationship structure exposes real conceptual sparsity rather than gaps that are artifacts of divergent terminology.
Entity-resolved attribution and competitive intelligence. Entity resolution normalizes assignee and inventor variants to canonical nodes, which lets the graph attribute filings and research accurately and build co-assignee and citation networks rather than a document list.
Provenance-grounded AI. The ontology and knowledge graph give AI agents a structured, provenance-tracked foundation to reason over, which improves the accuracy of agentic analysis and makes its results traceable to the specific patents and papers that support them.
Where Cypris fits
Cypris organizes a corpus of more than 500 million patents and scientific papers through a proprietary R&D ontology. That ontology is the core of the platform: it defines how technologies, claims, materials, methods, and research relate, so Cypris reasons over an entity-resolved relationship structure rather than only matching keywords. This structure powers dense semantic retrieval organized by concept, white space analysis that exposes genuine conceptual gaps, and competitive intelligence that attributes activity to canonical organizations and technology areas. Cypris Q, the platform's agentic layer, reasons over this provenance-tracked foundation, which is what makes its multi-step analysis both reliable and traceable to real patents and papers, consistent with graph-grounded retrieval approaches. Agentic Monitoring tracks a technology area over time against the same structure. Cypris provides enterprise API partnerships with OpenAI, Anthropic, and Google, so AI agents can query the structured corpus programmatically, and it is built with enterprise-grade security. Cypris serves hundreds of enterprise customers across pharmaceuticals, chemicals, advanced materials, energy, and other regulated industries.
FAQ
What is an ontology in R&D and patent intelligence?
An ontology in R&D and patent intelligence is a formal, machine-readable specification of the concepts in the domain and the relationships among them, defined as an explicit specification of a conceptualization. It sets out the entity types, such as technologies, materials, methods, and claims, and the relations that connect them. This lets a platform reason over connections between patents and scientific literature rather than treating documents as isolated.
How is an ontology different from a taxonomy?
An ontology differs from a taxonomy in expressiveness. A taxonomy arranges terms in a hierarchy, while an ontology also encodes non-hierarchical, typed relationships and constraints, such as a material being used in a process. This richer structure is what allows multi-hop reasoning across patents and research rather than simple category lookup.
What is a knowledge graph for patents?
A knowledge graph for patents represents patents, scientific papers, assignees, inventors, technologies, and materials as nodes connected by typed edges, commonly expressed as subject-predicate-object triples. It applies an ontology's schema to real data so relationships are explicit and queryable. This turns a document collection into a structure that supports declarative queries and multi-hop traversal.
How is a knowledge graph built from patent text?
A knowledge graph is built from patent text through named-entity recognition and relation extraction to convert unstructured text into triples, entity resolution to normalize variant names to canonical nodes, and provenance tracking so each assertion links back to its source document. The quality of these steps determines the reliability of the graph. Poor entity resolution, for example, fragments an organization across many nodes and distorts attribution.
Why do knowledge graphs matter for AI in patent research?
Knowledge graphs matter for AI in patent research because they ground generative models on real, connected entities, which improves accuracy and traceability. A model generating from unstructured text alone can assert unsupported claims, whereas one conditioned on a provenance-tracked graph constrains its answers to actual patents and papers. This is essential where conclusions must be verifiable.
What is GraphRAG and how does it differ from standard RAG? GraphRAG is graph retrieval-augmented generation. Standard RAG retrieves isolated text passages to condition a model's output, while GraphRAG retrieves connected subgraphs, so the model reasons over entities and their relationships and can answer multi-hop questions. This suits patent intelligence, where questions often require traversing links between technologies, research, and organizations.
How does an ontology improve white space analysis?
An ontology improves white space analysis by clustering patents and papers over defined relationships rather than by exact keywords, which exposes genuine conceptual gaps instead of gaps that are only artifacts of differing terminology. Because the sparsity reflects the domain structure, the identified white space corresponds to unclaimed technical territory. Cypris organizes its corpus of more than 500 million patents and scientific papers through a proprietary R&D ontology for this purpose.
How do knowledge graphs reduce AI hallucination in patent work?
Knowledge graphs reduce AI hallucination in patent work by constraining a model's outputs to real, connected entities with tracked provenance rather than letting it generate from unstructured text. Retrieval-augmented approaches, and graph-based retrieval in particular, condition generation on retrieved evidence, which improves factual accuracy and lets conclusions be traced to sources. This makes results verifiable against the underlying patents and papers.
Is a knowledge graph the same as a vector database?
A knowledge graph is not the same as a vector database. A vector database supports semantic similarity search over embeddings, while a knowledge graph represents explicit, typed relationships between entities. They are complementary: dense retrieval finds relevant documents, and the graph structures how those documents and entities relate. Cypris combines semantic retrieval with a proprietary R&D ontology.
Which teams benefit from ontology-based patent intelligence?
Ontology-based patent intelligence benefits R&D, innovation, IP, and strategy teams that need to understand how technologies relate, attribute activity to organizations, and find genuine white space. It is most valuable in research-intensive industries such as pharmaceuticals, chemicals, advanced materials, and energy. Cypris serves hundreds of enterprise customers across these industries.

Patent filings are a leading indicator of competitor R&D direction, and the lead time is a structural consequence of how the patent system operates. An application is filed at its priority date, well before the corresponding product reaches the market, and under the standard 18-month publication rule reflected in USPTO practice and PCT Article 21,⁵ it is not published until roughly eighteen months after that priority date. The interval between when a competitor commits R&D and when the public can observe it is therefore built into the system. The International Energy Agency treats patenting as a leading indicator of technological change in its innovation analysis,¹ and the same logic holds across sectors: a competitor's published filings reveal committed R&D direction ahead of the market, and studies of the linkage between scientific publication and patenting document a measurable lag between the two that compounds the observable lead time.² For R&D and competitive intelligence teams, this makes patents one of the most reliable forward-looking competitive signals available.
Reading that signal well requires structured analysis rather than filing counts, and several technical steps determine its accuracy. First, the unit of analysis should be the patent family, not the individual document, because a single invention generates multiple applications across jurisdictions; counting documents rather than families overstates activity and double-counts international coverage. Second, filings must be located in the technology space using classification codes, principally the Cooperative Patent Classification and International Patent Classification systems, which assign standardized technology categories independent of the applicant's terminology. Third, activity must be attributed through assignee disambiguation, normalizing the many name variants, subsidiaries, and transliterations of an organization to a single canonical entity, because unresolved assignee names fragment a competitor's portfolio and distort the picture. Fourth, the analysis should read the trend over time rather than the latest counts, because the most recent eighteen-to-twenty-four months of data are systematically under-represented by publication lag, so apparent recent declines are usually artifacts rather than real slowdowns.
Two network structures add depth beyond volume. Forward and backward citation analysis situates a competitor's filings in the flow of prior art: backward citations reveal the foundations a filing builds on, and forward citations indicate influence and where a technology is being extended. Co-assignee and knowledge-search network analysis reveals partnerships, academic-industry pipelines, and the coupling between organizations, which shape a competitor's future direction; network-embedding methods over these structures are an established competitive-intelligence technique.³ Scientific literature strengthens the signal further, because research is published before it is patented and patents are filed before products ship, so combining the two sources extends the observable lead time; the scientific footprint within a competitor's filings can be traced through their non-patent references.⁴
What competitor filings reveal
Technology direction. The classification areas where a competitor is filing show where R&D is being committed, often well before those commitments appear in products.
Intensity and momentum. The distribution and rate of change of filing activity across technology areas indicate priorities, and shifts in filing momentum signal changes in strategy earlier than raw counts.
Adjacent moves. Filings in classifications adjacent to a competitor's current products can signal diversification or expansion before it is announced.
Research foundations. The non-patent references and scientific literature a competitor's filings build on show the research base behind their direction, and rising related research is an earlier signal still.
Collaboration structure. Co-assignee patterns and citation coupling reveal partnerships and academic-industry pipelines; network analysis of these relationships is an established competitive-intelligence method.³
How to read competitor R&D direction
Define the competitors and the technology space, scoping the latter with classification codes so the boundary is standardized and reproducible.
Resolve assignees to canonical entities and aggregate to the patent-family level, so activity is attributed accurately and international coverage is not double-counted.
Cluster filings by concept using semantic analysis over the classification and text, so related work groups together regardless of terminology.
Analyze filing momentum as a time series, discounting the most recent windows for publication lag, since direction is visible in trends rather than in the latest bar.
Connect filings to their non-patent references and to the scientific literature, to extend the lead time and expose the research foundations.
Monitor continuously, because competitor direction is revealed by how activity shifts, and continuous monitoring captures those shifts as they publish.
Where Cypris fits
Cypris supports competitive intelligence across a corpus of more than 500 million patents and scientific papers, organized through a proprietary R&D ontology. The ontology and its entity resolution are what turn filings into direction: they normalize assignees to canonical organizations, aggregate to the family level, and cluster activity by concept, so a team sees where a competitor is moving rather than a list of documents. Dense semantic search across patents and scientific literature connects filings to their research foundations, which extends the lead time on the signal, and citation and co-assignee structures expose collaboration and influence. Cypris Q, the platform's agentic layer, lets teams analyze competitor direction conversationally and chain the attribution, clustering, and time-series analysis. Agentic Monitoring is central to this use case: it tracks defined competitors and technology areas over time and flags new filings and research as they publish, so competitive intelligence is continuous rather than a one-time report. Cypris provides enterprise API partnerships with OpenAI, Anthropic, and Google, so AI agents can query the corpus programmatically, and it is built with enterprise-grade security. Cypris serves hundreds of enterprise customers across pharmaceuticals, chemicals, advanced materials, energy, and other regulated industries.
FAQ
How do patent filings reveal competitor R&D direction?
Patent filings reveal competitor R&D direction because an application is filed at its priority date, before the product ships, and is published only about eighteen months later under the standard publication rule. This built-in lag means published filings show committed R&D ahead of the market. Reading the direction requires attributing filings to competitors and technology areas and analyzing where activity concentrates and shifts.
What is the 18-month publication rule?
The 18-month publication rule is the standard practice, reflected in USPTO procedure and PCT Article 21, under which a patent application is published approximately eighteen months after its earliest priority date. It creates a predictable interval between filing and public visibility. It is also why the most recent windows of filing data are under-represented and should not be read as slowdowns.
Why analyze patent families instead of individual documents?
Analyzing patent families instead of individual documents avoids double-counting, because a single invention generates multiple applications across jurisdictions. Counting documents overstates activity and conflates international coverage with genuine volume. The family is the correct unit for measuring how much distinct R&D a competitor is committing.
What role do classification codes play?
Classification codes, principally the Cooperative Patent Classification and International Patent Classification systems, assign standardized technology categories to filings independent of the applicant's wording. They let an analyst locate and compare activity in a technology space reproducibly. This is more reliable than keyword filtering, which varies with drafting style.
Why is assignee disambiguation important?
Assignee disambiguation is important because organizations appear under many name variants, subsidiaries, and transliterations, and unresolved names fragment a competitor's portfolio across multiple entities. Normalizing these to a single canonical entity is what makes attribution and trend analysis accurate. Poor disambiguation systematically distorts competitive intelligence.
How do citation networks support competitive intelligence?
Citation networks support competitive intelligence by situating filings in the flow of prior art. Backward citations reveal the foundations a filing builds on, and forward citations indicate influence and where a technology is being extended. Co-assignee and knowledge-search network analysis additionally reveals partnerships and academic-industry pipelines.
Why combine patents with scientific literature?
Combining patents with scientific literature extends the observable lead time, because research is published before it is patented and patents precede products. Rising research associated with a competitor, followed by early filings, is an earlier and stronger signal than filings alone. The scientific footprint within filings can be traced through their non-patent references.
Why not just count competitor patent filings?
Counting filings alone is misleading because recent counts are depressed by publication lag and raw volume does not indicate direction. The informative signal is which classification areas activity concentrates in and how that distribution changes over time. Family-level aggregation, classification analysis, and time-series momentum are what reveal direction.
Why is continuous monitoring important for competitive intelligence? Continuous monitoring is important because competitor direction is revealed by how activity changes, which a one-time report cannot capture, and because new filings and research publish constantly. A shift in a competitor's focus is only visible if the area is tracked over time. Cypris uses Agentic Monitoring to track competitors and technology areas and flag new activity as it publishes.
Which teams read competitor R&D direction from patents?
Reading competitor R&D direction from patents is done by competitive intelligence, R&D, innovation, strategy, and corporate development teams that need forward-looking awareness of competitor moves. It is most valuable in research-intensive industries such as pharmaceuticals, chemicals, advanced materials, and energy. Cypris serves hundreds of enterprise customers across these industries.

Wide-bandgap power semiconductors have become one of the most strategically important and most litigated areas in electronics, and their patent landscape is distinctive because value and risk are spread across the full stack from crystal to module. Silicon carbide and gallium nitride switch faster, tolerate higher voltages and temperatures, and lose less energy than conventional silicon, which is why they are central to electric-vehicle drivetrains, fast charging, solar and grid power conversion, and the power delivery of AI data centers; peer-reviewed reviews document these comparative properties and the trade-offs between the two materials.¹,² The intellectual property divides across several regions, each with different owners and maturity: the substrate and bulk-crystal growth that produces the raw material; the epitaxy that grows the active layers, including gallium nitride on silicon; the device design, such as the transistor and diode structures, whose failure and reliability modes are a distinct engineering concern;³ the packaging and thermal-management technologies that manage heat and switching losses;² and the application-level integration into drivetrains and power systems, where gallium-nitride high-electron-mobility transistors are increasingly used.⁴ Because a competitive product depends on several of these layers, freedom-to-operate is a multi-layer analysis rather than a single clearance.
The landscape is defined by intense litigation. Established wide-bandgap developers with deep substrate and device portfolios have asserted their patents against newer entrants, and the disputes have moved through trade-enforcement bodies and the federal courts. In a US International Trade Commission investigation into certain semiconductor devices, a final initial determination issued on December 2, 2025 found a violation as to one asserted patent and no violation as to a second, with the Commission determining to review the decision in part, a proceeding that remained under Commission review as of early 2026.⁶ In parallel, a wide-bandgap developer has asserted foundational gallium-nitride and silicon-carbide patents against a competitor in US federal court, with the case active on the district-court docket.⁷ Parallel proceedings are underway in other jurisdictions. This pattern signals a maturing field in which foundational substrate, epitaxy, and device patents create real barriers, and in which a single infringement finding in a key market can reshape a competitor's access to it. The ownership picture is concentrated but contested: across the Cypris corpus of more than 500 million patents and scientific papers, the most active assignees in the gallium-nitride power-device set are incumbent integrated device manufacturers, led by Japanese and European firms such as Mitsubishi Electric, Fuji Electric, Infineon, Toshiba, and Rohm, together with foundries and a small number of US developers, of which one substrate-and-device specialist is the clearest pure-play; the set holds on the order of 80,000 families on an indicative basis and grew roughly 2.4 times between 2018 and 2024, with China and the United States leading on assignee geography, followed by Japan, Germany, and South Korea. Because applications publish about eighteen months after filing, the most recent device and packaging filings are under-represented (2025 counts are partial), so the current frontier is more active than granted-patent counts suggest.
The strategic question is which layer to own, and the answer differs by material. In silicon carbide, the substrate and bulk-crystal layer is a durable barrier because high-quality crystal growth is difficult and capital-intensive, so much of the defensible value sits upstream. In gallium nitride, where devices are often grown on silicon wafers, the contested ground is more in epitaxy, device architecture, and packaging, and the litigation has concentrated there. Across both, packaging and thermal management are rising in importance as switching speeds increase,² and ultra-wide-bandgap approaches are an emerging frontier beyond today's materials.⁵ Reading the landscape by material, layer, and owner, and tracking the live proceedings, is what separates a workable position from a blocked one.
What creates FTO risk in wide-bandgap power semiconductors
Substrate and crystal-growth claims. These cover bulk silicon-carbide crystal and wafer production, a capital-intensive, upstream layer that is a durable barrier in silicon carbide.
Epitaxy claims. These cover the growth of active layers, including gallium nitride on silicon, a heavily contested layer central to gallium-nitride litigation.
Device-design claims. These cover transistor and diode structures and their edge terminations and gate designs, whose reliability and failure modes are a frequent center of disputes.³
Packaging and module claims. These cover thermal management, interconnection, and module construction, a layer rising in importance as switching speeds increase.²
Application-integration claims. These cover integration into drivetrains, chargers, and power systems, so a device can be free at the component level and constrained in a specific application.⁴
How AI-powered landscape and FTO analysis helps
A multi-layer, cross-border, heavily litigated landscape is beyond manual clearance. AI-powered analysis addresses this with semantic search that retrieves relevant substrate, epitaxy, device, and packaging claims regardless of terminology, attribution that normalizes incumbent and challenger owners to canonical entities across jurisdictions, claim-level analysis that separates the layers, and continuous monitoring that tracks new filings and the live disputes. Because wide-bandgap advances appear in scientific literature before they are patented, reading both patents and literature gives earlier warning of where the field is extending.
Where Cypris fits
Cypris runs patent landscape and freedom-to-operate analysis for multi-layer, litigated fields such as wide-bandgap power semiconductors across a corpus of more than 500 million patents and scientific papers, organized through a proprietary R&D ontology. The ontology clusters the landscape by material and layer, substrate, epitaxy, device, packaging, and application, and normalizes owners to canonical entities across jurisdictions, so a team sees how rights are distributed between incumbents and challengers rather than a flat list. Semantic search across patents and scientific literature surfaces relevant claims regardless of terminology and connects filings to the underlying materials and device research, which is where next-generation structures emerge first. Cypris Q, the platform's agentic layer, lets teams run landscape and FTO analysis conversationally and chain the attribution, clustering, and claim-level analysis across layers, and Agentic Monitoring tracks the landscape over time and flags new filings and developments as they publish. Cypris provides enterprise API partnerships with OpenAI, Anthropic, and Google, and is built with enterprise-grade security. Cypris serves hundreds of enterprise customers across pharmaceuticals, chemicals, advanced materials, energy, and other regulated industries.
FAQ
Why are wide-bandgap power semiconductors a patent hotspot? Wide-bandgap power semiconductors are a patent hotspot because silicon carbide and gallium nitride enable more efficient power electronics for electric vehicles, fast charging, renewables, and AI data centers, creating a large and fast-growing market. Value and risk are spread across substrate, epitaxy, device, and packaging layers. That breadth, plus intense competition, has produced heavy litigation.
What layers does the SiC and GaN landscape cover? The landscape covers substrate and bulk-crystal growth, epitaxy, device design, packaging and modules, and application integration. In silicon carbide the substrate layer is a durable upstream barrier, while in gallium nitride the contested ground is more in epitaxy, device design, and packaging. Freedom-to-operate must span the relevant layers for each material.
Why is this field so heavily litigated? The field is heavily litigated because foundational substrate, epitaxy, and device patents create real barriers, incumbents hold deep portfolios, and fast-growing challengers are building their own. Disputes have moved through the US International Trade Commission and the federal courts, with a December 2025 ITC determination finding a violation as to one patent and none as to another, and a separate district-court case over foundational gallium-nitride and silicon-carbide patents. A single ruling in a key market can reshape competitive access.
Where is the white space in wide-bandgap semiconductors? The white space includes packaging and thermal management as switching speeds rise, device architectures that design around crowded structures, gallium-nitride epitaxy and integration approaches, and application-level integration into drivetrains and power systems. The silicon-carbide substrate layer is a durable barrier held by incumbents. The higher-value opportunities are in packaging, device design, and integration.
How do silicon carbide and gallium nitride differ in the patent picture? They differ because silicon carbide value concentrates upstream, in difficult, capital-intensive crystal growth, while gallium nitride, often grown on silicon, concentrates contested IP in epitaxy, device architecture, and packaging. The litigation patterns reflect this. Freedom-to-operate strategy should therefore be tailored to the material.
Why does wide-bandgap analysis need scientific literature? Wide-bandgap analysis needs scientific literature because materials, device, and packaging advances appear in research before they are patented, so the literature gives the earliest signal. Analyzing patents alone gives a lagging view. Cypris analyzes both across more than 500 million patents and scientific papers.
What software helps analyze the SiC and GaN patent landscape? Software for the wide-bandgap landscape should cluster activity by material and layer, resolve incumbent and challenger owners to canonical entities across jurisdictions, search patents and scientific literature semantically, and monitor active litigation and new filings continuously. Cypris does this across more than 500 million patents and scientific papers using a proprietary R&D ontology, semantic search, Cypris Q, and Agentic Monitoring.
Which teams use wide-bandgap patent landscape analysis? Wide-bandgap patent landscape analysis is used by R&D, IP, and strategy teams at semiconductor, automotive, power-electronics, and energy companies, as well as investors assessing the sector. Because the field is litigated across the full stack and across borders, structured analysis is essential. Cypris serves hundreds of enterprise customers across advanced materials, energy, and other research-intensive industries.
