Portfolio overview

C. Rob. Hammerstein Gmbh & Co. KG has been granted 25 US utility patents between 2015 and 2018, placing C. Rob. Hammerstein Gmbh & Co. KG at #11,952 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.7 claims per patent with primary concentration in B60N (SEATS SPECIALLY ADAPTED FOR VEHICLES; VEHICLE PASSENGER ACCOMMODATION NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, C. Rob. Hammerstein Gmbh & Co. KG is one of the more focused assignees in the PatentsView dataset. By volume, C. sits between Bluefin Payment Systems, Llc (25 patents, rank #11,948) and China Pharmaceutical University (25 patents, rank #11,956) - the closest US assignees by grant volume. The composite Innovation Score of 32.4/100 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 0 grants, compared with 25 in the 2015–2019 window, a -100% 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. C. Rob. Hammerstein Gmbh & Co. KG's 11.7 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 16 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
