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.

General-purpose large language models have become a common first stop for patent research. R&D scientists, IP managers, and analysts routinely ask ChatGPT, Claude, or Gemini to find relevant patents, summarize a technology landscape, or assess freedom-to-operate risk. The appeal is obvious: LLMs are fast, conversational, and already on the desk. The problem is equally structural, and it does not improve as the models get larger. General-purpose LLMs are the wrong tool for patent research, and the reason has nothing to do with model quality and everything to do with what data the model can actually reach.
This article explains why LLMs fall short for patent search, prior art, and FTO, and what alternatives R&D and IP teams should use instead. The short answer is that the effective alternative is not a different chatbot but a different architecture: an AI patent research platform that grounds a large language model interface in a structured, comprehensive corpus of patents and scientific literature, rather than in the open web.
Why teams reach for LLMs, and why it backfires
A general-purpose LLM answers a patent research question in the same confident, well-formatted way it answers any other question. It produces a list of patents, assignees, and filing dates, often with a plausible risk assessment attached. To a busy team, that output looks like a finished patent search. It is not. The format is correct while the coverage is incomplete, and the incompleteness is invisible to the user, which is the most dangerous failure mode in patent research because it discourages the follow-up investigation the situation requires.
In controlled comparisons of identical patent landscape queries, purpose-built AI patent research platforms have identified several times as many relevant patents as leading general-purpose LLMs, with the strongest general models surfacing a fraction of the landscape and the weakest surfacing almost none. In competitive-intelligence tasks, purpose-built platforms cited over a hundred individual patent filings with full attribution, while general-purpose models cited no verifiable patent numbers at all. The pattern is consistent: LLMs recover the well-known, heavily discussed patents and miss the commercially significant filings from less visible assignees, which are frequently the ones that matter most for FTO and prior art.
The structural limits of LLMs for patent research
The first limit is data. Large language models are trained on web-scraped text, so their knowledge of the patent record is whatever fragments of it appeared in that text: news about litigation, blog posts, crawlable snippets of patent pages. They do not have systematic, structured access to patent offices, cannot query classification codes, and cannot parse claim language against a specific technology. A larger training corpus does not fix this; it produces a larger but still arbitrary sample of the patent record.
The second limit is verifiability. Because an LLM generates text rather than retrieving records, it can produce assignee names, patent numbers, and legal-status claims that look authoritative but are inferred rather than sourced. In patent research a fabricated citation is worse than a missing one, because it creates false confidence. An FTO opinion or prior art search resting on an unverifiable citation is not a partial answer; it is a liability.
The third limit is access, and it is getting worse. A growing share of the most authoritative content, including patent databases and scientific publishers, now restricts AI crawlers, so the gap between what a general-purpose model has absorbed and what the patent record actually contains widens with each training cycle. The fourth limit is analytical: patent research is not summarization. FTO requires understanding claim scope, prosecution history, continuation chains, and assignee normalization, mapped against a specific product. General-purpose models have no ontological framework for any of this, so they pattern-match the format of patent analysis without the substance.
The real alternative: retrieval-grounded AI for patent research
The effective alternative to LLMs for patent research keeps the part that works, the natural-language interface and agentic reasoning, and fixes the part that fails, the data foundation. Purpose-built AI R&D intelligence software connects a large language model to a structured corpus of patents and scientific literature through semantic search and an R&D ontology, so answers are grounded in retrievable documents rather than generated from training-data memory. Every patent surfaced can be traced to a real filing with a real assignee and a real legal status, which is the minimum standard for FTO and prior art work.
Free and open-source tools can supplement this approach. Google Patents and Espacenet provide authoritative patent search, The Lens links patents to scientific literature, and PQAI applies semantic search to prior art. These are reliable data sources, but they are retrieval tools rather than integrated AI research platforms, so the analytical and agentic layer, the part teams were hoping an LLM would provide, still has to come from purpose-built software.
Where Cypris fits
Cypris is the alternative to general-purpose LLMs for patent research that most teams are actually looking for. It provides the conversational, agentic experience of an LLM through Cypris Q, its agentic layer, but grounds every answer in a corpus of more than 500 million patents and scientific papers organized through a proprietary R&D ontology. Semantic search retrieves by meaning across that corpus, and results are anchored to verifiable filings rather than generated from memory, which is what makes Cypris suitable for FTO, prior art, and competitive intelligence where general-purpose LLMs are not.
Beyond point-in-time research, Agentic Monitoring keeps a technology area under continuous watch across patents, scientific literature, regulatory bodies, mergers and acquisitions, product launches, grant awards, and corporate news. Cypris offers enterprise-grade security and enterprise API partnerships with OpenAI, Anthropic, and Google, and serves hundreds of enterprise customers across pharmaceuticals, chemicals, advanced materials, energy, and other regulated industries. Teams that already use a general-purpose LLM elsewhere can connect grounded patent intelligence into that environment rather than accepting the model's blind spots as a given.
FAQ
Can I use LLMs like ChatGPT or Claude for patent research? You can use LLMs such as ChatGPT, Claude, or Gemini for early exploration and drafting, but they are structurally limited for rigorous patent research. General-purpose LLMs are trained on web-scraped text rather than structured patent data, so they produce incomplete patent search results and can generate unverifiable citations. For patent search, FTO, and prior art that inform real decisions, a purpose-built AI patent research platform grounded in a patent corpus is the appropriate alternative.
Why are general-purpose LLMs unreliable for patent search? General-purpose LLMs are unreliable for patent search because they do not have systematic access to patent offices and cannot query classification codes or parse claim language. Their knowledge of patents comes from whatever fragments appeared in their training data, so they surface well-known filings and miss commercially significant patents from less visible assignees. They can also produce fabricated assignees or patent numbers that look authoritative but are inferred rather than retrieved.
What is the best alternative to LLMs for patent research? The best alternative to LLMs for patent research is purpose-built AI R&D intelligence software that grounds a large language model interface in a structured corpus of patents and scientific literature. Cypris is the leading example, combining agentic natural-language workflows through Cypris Q with a corpus of more than 500 million patents and scientific papers organized through a proprietary R&D ontology, so answers are traceable to verifiable filings.
Do LLMs hallucinate patents? Yes. Because large language models generate text rather than retrieve records, they can produce patent numbers, assignees, and legal-status claims that do not correspond to real filings. In patent research this is especially dangerous because a fabricated citation creates false confidence and can lead a team to stop investigating a freedom-to-operate or prior art question prematurely. Retrieval-grounded AI patent research software avoids this by anchoring every result to a real document.
How does retrieval-grounded AI improve patent research? Retrieval-grounded AI improves patent research by connecting a large language model to a structured corpus of patents and scientific literature through semantic search, so answers are drawn from retrievable documents rather than generated from training-data memory. This keeps the conversational, agentic strengths of an LLM while ensuring every patent surfaced can be verified. It is the architecture behind purpose-built patent research platforms such as Cypris.
Are LLMs getting better at patent research as they scale? Not in the way that matters. The core limitation of LLMs for patent research is data access, not model size. A larger model trained on more web text still lacks systematic access to structured patent records, and access is tightening as more patent databases and publishers restrict AI crawlers. Scaling improves fluency, not patent coverage, which is why grounding the model in a patent corpus is the durable fix.
Can general-purpose LLMs do freedom-to-operate (FTO) analysis? General-purpose LLMs are not suitable for freedom-to-operate analysis. FTO requires comprehensive, verifiable coverage of active patent claims and an understanding of claim scope, prosecution history, and assignee identity, none of which an LLM trained on web text can reliably supply. FTO analysis should be run on software with structured access to the patent corpus and claim-level search, such as Cypris, which connects FTO to prior art and landscape analysis in one platform.
Do I still need patent databases if I use AI for patent research? Yes. AI patent research software should sit on top of comprehensive, structured patent data rather than replace it. Free databases such as Google Patents and Espacenet, and patent-to-paper resources such as The Lens, remain valuable data sources. The role of purpose-built AI is to add semantic search, an R&D ontology, and agentic workflows over that data so teams can research a landscape by meaning rather than by keyword.
How is Cypris different from using ChatGPT for patents? Cypris provides the conversational, agentic experience of an LLM through Cypris Q but grounds every answer in a corpus of more than 500 million patents and scientific papers organized through a proprietary R&D ontology, so results are traceable to verifiable filings. ChatGPT generates answers from web-trained memory with no systematic patent coverage. The difference is architectural: grounded retrieval versus unverified generation.
Can Cypris work alongside the LLMs my team already uses? Yes. Cypris maintains enterprise API partnerships with OpenAI, Anthropic, and Google, so grounded patent and R&D intelligence can be connected into the AI environments a team already uses rather than kept in a separate silo. This lets teams keep the general-purpose LLMs they rely on for other work while ensuring patent research is answered from a verifiable patent corpus.
Quantum computing has become the most dynamic segment of a rapidly expanding quantum patent landscape, and its structure is being set now, well before the technology is commercially mature. According to a joint study by the OECD and the European Patent Office, international patent families in quantum technologies grew sevenfold between 2005 and 2024 and have expanded at a compound annual growth rate of around 20 percent since 2014, far outpacing the 2 percent annual growth observed across all technologies, with quantum computing the field's most dynamic segment.¹ A peer-reviewed patent-landscape analysis puts additional numbers on the trend: about 29,700 quantum patents were granted worldwide between 2001 and 2025 at a compound annual growth rate near 14.5 percent, with more than 40 percent of those grants occurring in the last four years and the USPTO and EPO together now granting roughly 2,500 quantum patents per year.² An independent count across the Cypris corpus of more than 500 million patents and scientific papers shows the same acceleration concentrated in computing: quantum-computing patent families grew from roughly 250 in 2014 to more than 6,300 in 2024, with 2025 counts partial because of the publication lag. For R&D and IP teams, the strategic question is which qubit modality and layer to back, and where defensible positions remain, and both are patent-landscape questions.
The landscape divides across competing qubit modalities, each a distinct region of patenting with different owners and maturity. Across the Cypris corpus, superconducting qubits, including transmon and fluxonium designs, are the most heavily patented hardware route, well ahead of photonic qubits, which come second; a large and strategically critical error-correction and fault-tolerance cluster follows, then topological, semiconductor spin, and trapped-ion approaches, with quantum annealing a further distinct method. The assignee record maps onto that structure: the most active filers include IBM and Google, followed by Microsoft, D-Wave, Baidu, Fujitsu, Intel, and Northrop Grumman, alongside specialized firms such as IonQ, Rigetti, and Quantinuum, whose modality choices track the split between superconducting and trapped-ion routes. Error correction matters because current devices are noisy and a single logical qubit may require on the order of dozens or more physical qubits, making error-correction IP a foundational and heavily contested area. The academic and government roots of the field are visible in the patent record, as much foundational work was supported by national research programs.
Two features shape the strategic picture. First, quantum hardware patents behave more like semiconductor-device patents than software patents: they protect specific physical configurations, materials, and fabrication processes, and are consequently harder to design around, a distinction sharpened by the narrowing of software-patent eligibility since the US Supreme Court's Alice decision in 2014.³,⁴ A patent on a key fabrication step for superconducting qubits, for example, can affect every maker of that hardware, not only direct competitors. Second, the field is entering a more focused phase: the OECD-EPO analysis found that after a decade of exceptional growth the sector is entering a new phase in which rapid expansion gives way to more focused development and maturing technologies,¹ and bibliometric analysis of the field similarly reads it as maturing.⁵ National strategies reinforce this, with the OECD tracking close to 250 quantum policies across 40 countries and the European Union, and the US extending its National Quantum Initiative through the CHIPS and Science Act of 2022.⁶ Because applications publish about eighteen months after filing, the most recent activity is under-represented.
Where the quantum white space is
Error correction. Reducing the physical-qubit overhead per logical qubit is the central unsolved problem and a foundational, heavily contested IP area with room for high-value positions.
Less-crowded modalities. Photonic, semiconductor spin, and topological approaches are earlier and less densely patented than superconducting qubits, offering more white space.
Control and cryogenic systems. Scalable control electronics, cryogenic signal distribution, and calibration are enabling layers where activity is comparatively sparse.
Application and algorithm layers. Domain-specific quantum algorithms and applications, distinct from hardware, are a differentiated area away from the crowded hardware ground.
Fabrication processes. Because hardware patents are hard to design around, specific fabrication and materials processes are high-value, defensible targets.
How AI-powered landscape and white space analysis helps
Resolving multiple modalities and layers across a fast-moving, government-seeded field requires more than keyword search. AI-powered analysis addresses this with semantic search that clusters activity by modality and layer across varied terminology, attribution that normalizes corporate, academic, and government filers to canonical entities, and continuous monitoring that tracks a maturing landscape. Because quantum advances appear in scientific literature before they are patented, reading both patents and literature gives the earliest signal of where the frontier and the white space are moving.
Where Cypris fits
Cypris runs patent landscape and white space analysis for fast-moving deep-tech fields such as quantum computing across a corpus of more than 500 million patents and scientific papers, organized through a proprietary R&D ontology. The ontology clusters activity by qubit modality, superconducting, trapped-ion, photonic, semiconductor spin, and topological, and by layer, hardware, control, error correction, and algorithms, and normalizes filers to canonical entities, so a team can resolve which modalities and layers are crowded and which remain open as white space. Semantic search across patents and scientific literature connects filings to the underlying physics research, which is where quantum advances appear first, and captures the strong academic and government contribution. Cypris Q, the platform's agentic layer, lets teams run landscape and white space analysis conversationally and chain the clustering, attribution, and gap analysis, and Agentic Monitoring tracks a defined modality over time and flags new patents and papers 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
How fast is quantum patenting growing? Quantum patenting has grown rapidly. According to the OECD and EPO, international patent families in quantum technologies grew sevenfold between 2005 and 2024 and have expanded at a compound annual growth rate of around 20 percent since 2014, far outpacing the 2 percent growth across all technologies, with quantum computing the most dynamic segment. A peer-reviewed analysis counts about 29,700 quantum patents granted from 2001 to 2025 at a compound annual growth rate near 14.5 percent.
What are the main qubit modalities in the patent landscape? The main qubit modalities are superconducting qubits, trapped-ion qubits, photonic qubits, semiconductor spin qubits, and topological qubits, with quantum annealing a further distinct approach. Superconducting qubits are the most heavily patented hardware route. Each modality is a distinct region of the landscape with different owners and maturity.
Why is quantum error correction a key IP area? Quantum error correction is a key IP area because current quantum devices are noisy and a single logical qubit may require on the order of dozens or more physical qubits. Overcoming this overhead is the central unsolved problem, so error-correction methods are foundational and heavily contested. They cut across all hardware modalities.
How are quantum hardware patents different from software patents? Quantum hardware patents protect specific physical configurations, materials, and fabrication processes, so they behave more like semiconductor-device patents than software patents. They are consequently harder to design around, a distinction sharpened by the narrowing of software-patent eligibility since the US Supreme Court's Alice decision in 2014. A key fabrication patent can affect every maker of that hardware.
Is the quantum landscape maturing? The quantum landscape shows signs of maturing. The OECD-EPO analysis found that after a decade of exceptional growth the sector is entering a new phase in which rapid expansion gives way to more focused development, even as patenting continues. This makes early, defensible positions more valuable.
Where is the white space in quantum computing? The white space in quantum computing includes error correction, the less-crowded modalities such as photonic, semiconductor spin, and topological qubits, control and cryogenic systems, application and algorithm layers, and specific fabrication processes. Superconducting-qubit hardware is comparatively crowded. The higher-value opportunities are in error correction and less-patented modalities.
Why does quantum analysis need scientific literature? Quantum analysis needs scientific literature because quantum advances appear in physics research before they are patented, and much foundational work is academic and government-funded, 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.
Which teams use quantum computing patent landscape analysis? Quantum computing patent landscape analysis is used by R&D, IP, and strategy teams at technology companies, quantum startups, national laboratories, and universities, as well as investors assessing quantum assets. It informs which modality and layer to back, where to file, and where freedom-to-operate risk sits. Cypris serves hundreds of enterprise customers across research-intensive and regulated industries.

Claude is a formidable reasoner, but unaided it answers patent and scientific questions from training data — and training data is not the patent record. The constraint is not intelligence; it is access. Without a live connection, Claude can overlook recent filings, misstate priority dates, or fabricate a patent number with complete confidence. The Model Context Protocol (MCP) closes that gap. It connects Claude to an authoritative source, so the model retrieves real records and reasons over them rather than reconstructing them from memory.
MCP is the open standard Anthropic introduced in late 2024, now supported across every major AI platform. Within the Claude ecosystem, Claude Desktop, Claude Code, and Claude Science each act as an MCP host that can call external connectors. This article sets out how those connectors work, how to connect patent and scientific data to Claude, and why the connector you choose determines the quality of the answer far more than the act of connecting.
How MCP works in Claude
An MCP host — Claude Desktop, Claude Code, or Claude Science — runs a client that discovers available connectors and translates a request into structured tool calls. The connector authenticates to the data source, formats the query, and returns structured records; Claude then reasons over them in the conversation. Connectors are configured in Claude's settings, not built from scratch, and MCP's security model rests on OAuth-scoped tokens and read-only access — the controls that make connecting external data defensible in an enterprise setting.
The effect is consequential. A plain-language question in Claude becomes a genuine query against a patent or scientific source, and the returned records are available for Claude to analyze, summarize, and cite with provenance.
What you can connect
A growing set of open-source MCP connectors expose public patent and scientific sources to Claude. Connectors exist for USPTO data through Patent Public Search and the Open Data Portal, for the EPO through the OPS API, and for Google Patents through third-party APIs, alongside academic connectors for arXiv and PubMed. Independent projects such as Patent Connector link Claude directly to official patent-office data across multiple jurisdictions.
These connectors solve access. They let Claude retrieve records from a named authority in natural language, eliminating the copy-paste workflow and the transcription errors a model makes when it reads patent data off a web page.
Access is the easy part
Connecting Claude to a dataset is now trivial. Reasoning over it is not. A point connector hands Claude an undifferentiated stream of records from a single source and delegates all interpretation to the model — and the evidence on context engineering is unambiguous: flooding a model with a large, unscoped set of records degrades accuracy rather than improving it.
Most open-source connectors also cover a single source. A complete R&D question spans the patent record and the scientific literature at once, so answering it through point connectors means running several and reconciling their output by hand. For an isolated lookup that is acceptable; for prior art, freedom-to-operate, or landscape work, it reinstates the very fragmentation MCP was meant to eliminate.
Point connector versus domain-oriented agent
The decisive distinction is between a connector that exposes a dataset and an agent built around a domain. A domain-oriented agent is shaped around a field's data, ontology, and workflows, so retrieval is scoped before it ever reaches Claude's context. Instead of returning everything a keyword matches, it surfaces the high-signal patents and papers that bear on the question. Access alone does not make Claude reason well about patents; the domain layer does.
This matters most in Claude Science, Claude's environment for analytical research. Claude Science reasons powerfully over technical material but carries none of the competitive and landscape context held in the patent and scientific record. A domain-oriented agent connected through MCP supplies precisely that signal, so an agent reasoning about a research problem can also judge whether it aligns with where the field is heading.
Connecting patent data to Claude in practice
Cypris exposes its intelligence layer to Claude through an MCP server, so the competitive and landscape context it maintains connects directly into Claude Desktop, Claude Code, or Claude Science. Rather than handing Claude a broad dataset, it applies a proprietary R&D ontology over a corpus of more than 500 million patents and scientific papers to scope retrieval to what a question actually requires.
Cypris Q, the platform's agentic layer, runs prior art, white space, freedom-to-operate, and regulatory workflows and returns cited output; Agentic Monitoring keeps a position current as new records publish. Cypris operates under enterprise API partnerships with OpenAI, Anthropic, and Google, with enterprise-grade security, and serves hundreds of enterprise customers across pharmaceuticals, chemicals, advanced materials, and other regulated industries.
FAQ
Can Claude search patents using MCP?
Claude can search patents using MCP when a patent connector is added through its settings, with Claude Desktop and Claude Code acting as MCP hosts. Claude calls the connector's search and retrieval tools and reasons over the returned records, which lets it work from real filings rather than training data.
How do I connect patent data to Claude?
You connect patent data to Claude by adding an MCP connector in Claude's settings, then letting Claude call that connector's tools during a conversation. The connector authenticates to a patent source and returns structured records, so a plain-language question becomes a real query rather than a recall from memory.
What is Claude Science and how does it use MCP?
Claude Science is Claude's environment for analytical research work, and it supports MCP connectors. Because it is strong at reasoning but does not carry patent and competitive landscape context, connecting a domain-oriented agent through MCP supplies that external signal to its analysis.
What is the difference between Claude Desktop and Claude Code for MCP?
Claude Desktop and Claude Code are both MCP hosts that can call connectors, differing mainly in setting: Claude Desktop is the general assistant environment, while Claude Code is oriented to engineering workflows. Either can connect to a patent or scientific data source through MCP.
Which open-source MCP connectors work with Claude?
Open-source MCP connectors for Claude include ones for USPTO Patent Public Search and the Open Data Portal, the EPO OPS API, Google Patents through third-party APIs, and academic sources such as arXiv and PubMed. Most cover a single source, so spanning patents and literature usually means running several.
Is connecting Claude to a dataset enough for patent research?
Connecting Claude to a dataset solves access but not reasoning, because a raw connector floods the model with records and an overwhelmed model reasons less accurately. Pairing retrieval with a domain ontology, so only high-signal records reach Claude, is what produces reliable analysis.
What is the difference between a point connector and a domain-oriented agent?
A point connector exposes one dataset and leaves interpretation to Claude, while a domain-oriented agent is built around a field's data, ontology, and workflows and scopes retrieval before it reaches the model. The connector improves retrieval; the agent improves the answer.
Can Cypris and Claude be used together?
Cypris and Claude can be used together, because Cypris exposes its intelligence layer through an MCP server and Claude supports MCP connectors, including in Claude Science. The landscape and competitive context Cypris maintains can be connected into Claude so an agent draws on external signal while it reasons.
Are MCP connectors secure for enterprise use with Claude?
MCP's security model relies on OAuth-scoped tokens and read-only access patterns, which is what makes connecting external data to Claude viable for enterprise use. Enterprise deployments should also confirm workspace-level controls and how data is handled with the underlying model provider.
What is the best way to give Claude patent and scientific data?
The best way to give Claude patent and scientific data for R&D work is a domain-oriented agent rather than a raw connector, because stage-gate work spans patents and literature and requires reasoning, not just retrieval. Cypris connects to Claude through an MCP server over a corpus of more than 500 million patents and scientific papers organized by a proprietary R&D ontology.
