What this shows Rt-filtertechnik Gmbh stamps GRANTS-MICRO, MID-PACK, PHOTO-FINISH, CPC-NARROW, INNOV-THIN, CLAIMS-RICH, TYPE-FRNCORP, VEL-UP, BOOK-FULL. Volume places it #19,098 of 50,000; Innovation Score 28.9/100 sits in the top 71% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is Rofin-sinar Technologies Llc (±0 grants).
Rt-filtertechnik Gmbh has been granted 15 US utility patents between 2017 and 2025, placing Rt-filtertechnik Gmbh at #19,098 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.0 claims per patent with primary concentration in B01D (SEPARATION). As a Foreign Corporation, Rt-filtertechnik Gmbh is one of the more focused assignees in the PatentsView dataset. By volume, Rt-filtertechnik sits between Rofin-sinar Technologies Llc (15 patents, rank #19,071) and RWTH Aachen (15 patents, rank #19,079) - the closest US assignees by grant volume. The composite Innovation Score of 28.9/100 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. Between 2020 and 2024 the company received 8 grants, compared with 6 in the 2015–2019 window, a +33% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. 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. Rt-filtertechnik Gmbh's 15.0 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 3 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
