Portfolio overview

OFS Fitel, Llc has been granted 232 US utility patents between 2015 and 2024, placing OFS Fitel, Llc at rank #1,753 across all assignees tracked by PlainPatent. This portfolio spans 54 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.8 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a US Corporation, OFS Fitel, Llc is one of the broader-portfolio assignees in the PatentsView dataset. By volume, OFS sits between Covestro Llc (232 patents, rank #1,749) and Citibank, N.a. (231 patents, rank #1,757) - the closest US assignees by grant volume. The composite Innovation Score of 54.4/100 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 56 grants, compared with 176 in the 2015–2019 window, a -68% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. OFS Fitel, Llc's 14.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 54 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark OFS Fitel, Llc against peers pursuing similar technology classes.

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.
