Portfolio overview

BJB Gmbh & Co. KG has been granted 33 US utility patents between 2016 and 2025, placing BJB Gmbh & Co. KG at rank #9,447 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.0 claims per patent with primary concentration in F21V (FUNCTIONAL FEATURES OR DETAILS OF LIGHTING DEVICES OR SYSTEMS THEREOF; STRUCTURAL COMBINATIONS OF LIGHTING DEVICES WITH OTHER ARTICLES, NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, BJB Gmbh & Co. KG is one of the more focused assignees in the PatentsView dataset. By volume, BJB sits between Beihai HKC Optoelectronics Technology Co., Ltd. (33 patents, rank #9,443) and Biomedical Enterprises, Inc. (33 patents, rank #9,451) - the closest US assignees by grant volume. The composite Innovation Score of 38.0/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 20 grants, compared with 13 in the 2015–2019 window, a +54% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. BJB Gmbh & Co. KG's 8.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark BJB Gmbh & Co. KG against peers pursuing similar technology classes.
