Overall rank by patents
#9,469
of 50,000 tracked assignees
USPTO PatentsView assignee record - 33 granted patents across 45 technology areas, recorded in grant years 2020–2025. Grant-trend analysis is cross-referenced to USPTO Patent Public Search; it does not measure application filings, current R&D, or legal strength. Primary class: G10K (SOUND-PRODUCING DEVICES; METHODS OR DEVICES FOR PROTECTING AGAINST, OR FOR DAMPING, NOISE OR OTHER ACOUSTIC WAVES IN GENERAL; ACOUSTICS NOT OTHERWISE PROVIDED FOR).
The verdict
According to USPTO PatentsView, Center ranks #9,469 of 50,000 tracked US assignees by granted-patent volume, with 33 patents across 45 technology areas.

What this shows Center FOR Advanced Meta-materials stamps GRANTS-SMALL, UPPER-Q, PHOTO-FINISH, CPC-WIDE, INNOV-STRONG, CLAIMS-PAR, TYPE-FRNCORP, SPAN-YRS, BOOK-RICH. Volume places it #9,469 of 50,000; Innovation Score 62.6/100 sits in the top 2% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is C3.ai, Inc. (±0 grants).
Center FOR Advanced Meta-materials has been granted 33 US utility patents between 2020 and 2025, placing Center FOR Advanced Meta-materials at #9,469 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 45 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.2 claims per patent with primary concentration in G10K (SOUND-PRODUCING DEVICES; METHODS OR DEVICES FOR PROTECTING AGAINST, OR FOR DAMPING, NOISE OR OTHER ACOUSTIC WAVES IN GENERAL; ACOUSTICS NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Center FOR Advanced Meta-materials is one of the more focused assignees in the PatentsView dataset. By volume, Center sits between C3.ai, Inc. (33 patents, rank #9,464) and Calera Corporation (33 patents, rank #9,472) - the closest US assignees by grant volume. The composite Innovation Score of 62.6/100 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 2020 through 2025, with 33 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. Center FOR Advanced Meta-materials's 11.2 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 45 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
