Portfolio overview
Surftech Corporation has been granted 11 US utility patents between 2015 and 2019, placing Surftech Corporation at rank #25,311 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.6 claims per patent with primary concentration in C08G (MACROMOLECULAR COMPOUNDS OBTAINED OTHERWISE THAN BY REACTIONS ONLY INVOLVING UNSATURATED CARBON-TO-CARBON BONDS). As a US Corporation, Surftech Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Surftech sits between Structo Pte. Ltd. (11 patents, rank #25,307) and Swift Solar, Inc. (11 patents, rank #25,315) - the closest US assignees by grant volume. The composite Innovation Score of 25.6/100 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 11 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. Surftech Corporation's 11.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Surftech Corporation against peers pursuing similar technology classes.

How to use this portfolio
Surftech's 11 grants land it in the top 82% by Innovation Score, but volume alone doesn't tell you where the strength sits.
- Read that count against the largest US assignees before treating it as dominance - Surftech ranks #25,311 of 50,000. Top 50 holders
- Most of this portfolio concentrates in C08G - see who else leads that technology area. C08G leaders
- 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.
