Portfolio overview
Rosenberger Technologies Co., Ltd. has been granted 26 US utility patents between 2021 and 2022, placing Rosenberger Technologies Co., Ltd. at #11,791 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.0 claims per patent with primary concentration in H01Q (ANTENNAS, i.e. RADIO AERIALS). As a Foreign Corporation, Rosenberger Technologies Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Rosenberger sits between Reestar International Limited (26 patents, rank #11,783) and Research Products Corporation (26 patents, rank #11,791) - the closest US assignees by grant volume. The composite Innovation Score of 51.0/100 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 2022, with 26 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. Rosenberger Technologies Co., Ltd.'s 16.0 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 8 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
