Turn declared SEPs
into defensible
claim charts
What happens when SEP evidence
becomes your negotiation weak spot?
It starts with a declared patent list.
Then one patent cannot be mapped cleanly to the right clause of the cellular standard. Another depends on a standard version that has changed. Another looks essential, but the claim language and the TS language do not line up.
Before long, the negotiation is no longer about who owns more declared SEPs.
It is about who can prove which patents are truly essential.
For SEP teams, weak claim charts do not just slow review. They weaken licensing leverage, patent pool submissions, litigation preparation, and portfolio decisions.

Find the real SEP signalinside declared portfolios
Move beyond declaration counts. Patsnap Eureka helps identify which patents can be supported by claim-to-standard evidence and which cannot, so teams focus on the SEP assets that actually hold up under scrutiny, whether for licensing, pool submission, or enforcement.
Inspect every limitation mapping, line by line
Each claim is broken down into individual limitations and aligned with specific clause of the cellular standard. Reviewers can trace the logic for each limitation rather than accepting or rejecting a summary conclusion. That level of granularity is fully automated.
Turn claim charts into business leverage
Get a conclusion, not a classification to interpret. The report includes a patent technical summary, the full limitation-level claim chart, an essentiality conclusion, and a legal disclaimer. It exports as PDF or Word, formatted to move from the analyst's screen to the negotiation table.
Built for scale and precision
SEP work demands
Full-coverage standard data, continuously updated
Patsnap Eureka covers cellular technical specifications across the radio access, core network, and system services domains, spanning 2G through 5G-Advanced. Coverage includes version histories from early drafts through frozen releases, with automatic tracking of standard modifications and patent legal status changes.
Precision matching that resolves the semantic gap
The gap between patent claim language and standard specification language is where essentiality analysis breaks down. PatSnap Eureka addresses this through a multi-layer retrieval pipeline that combines keyword matching, semantic search, reranking, LLM filtering, and citation relevance correction. Matched terms are highlighted at the phrase level — fully automated, no human post-processing.
