The evidence for SEP review, with the version pinned.

Deciding whether a patent is standard-essential has always meant manually cross-referencing claim language against thousands of pages of 3GPP specifications: slow, expensive, and hard to double-check once it's done.We built SEPPi to make that first step fast and verifiable.Enter a patent number, and get a claim-by-claim match against the real standard text, not just a confidence score.

1. 1

   Grounded in the standard

   Every match is tied to a specific 3GPP clause, not a black-box prediction.

2. 2

   Built to be checked

   Reports show the source standard text next to the result, so you can verify the reasoning yourself.

3. 3

   Claim-level, not patent-level

   SEPPi compares the actual claim language against standard provisions, not broad classifications.

Enter a patent number and SEPPi compares its claims against the 3GPP specifications, producing a matching report grounded in the relevant clauses.The clauses are cited not only from the latest TS but at the release in which the feature first entered the standard. Each report carries the standard text it relied on, so you can follow the analysis yourself.

For patent managers who need to know quickly whether a portfolio is standard-essential, companies preparing licensing negotiations, practitioners reviewing standards disputes, and patent attorneys drafting continuation claims against the standard's wording.

If a demand letter or licensing offer arrives with a list of patents, you can see which spec and clause each one touches before you hand the list to counsel.Paste up to 20 patent numbers in one order. Before you pay, each patent shows its candidate specs for free, so you order reports only for the ones you need.Each report compares every claim element against the standard text at a pinned version and marks the elements the standard does not describe. Every clause shows the release in which it entered the standard, so you can set it against the patent's priority date.SEPPi draws no conclusion on essentiality or infringement. Reports come as PDF, PPTX and DOCX, ready to pass to the counsel handling your review.

Review several patents at once

The name is inspired by "Standard Essential Patents Pick-up". It stands for picking out, from a mountain of patents, the ones worth reviewing for standard-essentiality, and we took the initials and shaped them into "SEPPi".
