Portfolio overview

Seasons 4, Inc. has been granted 29 US utility patents between 2015 and 2025, placing Seasons 4, Inc. at rank #10,760 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.7 claims per patent with primary concentration in F21S (NON-PORTABLE LIGHTING DEVICES; SYSTEMS THEREOF; VEHICLE LIGHTING DEVICES SPECIALLY ADAPTED FOR VEHICLE EXTERIORS). As a US Corporation, Seasons 4, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Seasons sits between Super Group Semiconductor Co., Ltd. (29 patents, rank #10,756) and Shanghai Oxi Technology Co., Ltd (29 patents, rank #10,764) - the closest US assignees by grant volume. The composite Innovation Score of 42.1/100 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 16 grants, compared with 13 in the 2015–2019 window, a +23% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Seasons 4, Inc.'s 19.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Seasons 4, Inc. 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.
