Portfolio overview

Walter R. Tucker Enterprises, Ltd has been granted 40 US utility patents between 2016 and 2025, placing Walter R. Tucker Enterprises, Ltd at rank #8,144 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.2 claims per patent with primary concentration in F21Y (INDEXING SCHEME ASSOCIATED WITH SUBCLASSES F21K, F21L, F21S and F21V, RELATING TO THE FORM OR THE KIND OF THE LIGHT SOURCES OR OF THE COLOUR OF THE LIGHT EMITTED). As a US Corporation, Walter R. Tucker Enterprises, Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Walter sits between Vector Products, Inc. (40 patents, rank #8,140) and Zing Semiconductor Corporation (40 patents, rank #8,148) - the closest US assignees by grant volume. The composite Innovation Score of 38.9/100 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 25 grants, compared with 15 in the 2015–2019 window, a +67% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Walter R. Tucker Enterprises, Ltd's 9.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Walter R. Tucker Enterprises, Ltd against peers pursuing similar technology classes.
