Portfolio overview

Paris Sciences ET Lettres has been granted 25 US utility patents between 2021 and 2025, placing Paris Sciences ET Lettres at #12,163 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 41 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.1 claims per patent with primary concentration in B01J (CHEMICAL OR PHYSICAL PROCESSES, e.g. CATALYSIS OR COLLOID CHEMISTRY; THEIR RELEVANT APPARATUS). As a Foreign Corporation, Paris Sciences ET Lettres is one of the more focused assignees in the PatentsView dataset. By volume, Paris sits between Out RAGE, Llc (25 patents, rank #12,154) and Pizzato Elettrica S.r.l. (25 patents, rank #12,162) - the closest US assignees by grant volume. The composite Innovation Score of 62.9/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Historical data spans 2021 through 2025, with 25 total grants over that period. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Paris Sciences ET Lettres's 15.1 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 41 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
