Portfolio overview

Custom Leathercraft MFG., Llc has been granted 6 US utility patents between 2015 and 2018, placing Custom Leathercraft MFG., Llc at rank #39,704 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.3 claims per patent with primary concentration in A45C (PURSES; LUGGAGE; HAND CARRIED BAGS). As a US Corporation, Custom Leathercraft MFG., Llc is one of the more focused assignees in the PatentsView dataset. By volume, Custom sits between Crystal Systems Corporation (6 patents, rank #39,700) and Cvitek Co. Ltd. (6 patents, rank #39,708) - the closest US assignees by grant volume. The composite Innovation Score of 20.5/100 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 0 grants, compared with 6 in the 2015–2019 window, a -100% 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. Custom Leathercraft MFG., Llc's 5.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Custom Leathercraft MFG., Llc against peers pursuing similar technology classes.
