Portfolio overview

Belgravia Wood Limited has been granted 40 US utility patents between 2020 and 2025, placing Belgravia Wood Limited at rank #7,988 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.5 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, Belgravia Wood Limited is one of the more focused assignees in the PatentsView dataset. By volume, Belgravia sits between BIG LIFT, Llc (40 patents, rank #7,984) and China Iwncomm Co., Ltd. (40 patents, rank #7,992) - the closest US assignees by grant volume. The composite Innovation Score of 52.0/100 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. Historical data spans 2020 through 2025, with 40 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Belgravia Wood Limited's 17.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 22 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Belgravia Wood Limited against peers pursuing 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.
