Portfolio overview

Sanford L.p. has been granted 131 US utility patents between 2015 and 2025, placing Sanford L.p. at rank #2,918 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.6 claims per patent with primary concentration in B43K (IMPLEMENTS FOR WRITING OR DRAWING). As a US Corporation, Sanford L.p. is one of the more focused assignees in the PatentsView dataset. By volume, Sanford sits between Kurita Water Industries Ltd. (131 patents, rank #2,914) and The Raymond Corporation (131 patents, rank #2,922) - the closest US assignees by grant volume. The composite Innovation Score of 43.5/100 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 75 in the 2015–2019 window, a -25% 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. Sanford L.p.'s 8.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, 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 Sanford L.p. 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.
