The verdict
Sylvan holds 11 US patents across 7 technology areas, rank #25,211 of 50,000 tracked assignees.
Sylvan R. Shemitz Designs, Inc. has been granted 11 US utility patents between 2015 and 2021, placing Sylvan R. Shemitz Designs, Inc. at rank #25,211 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.8 claims per patent with primary concentration in H05B (ELECTRIC HEATING; ELECTRIC LIGHT SOURCES NOT OTHERWISE PROVIDED FOR; CIRCUIT ARRANGEMENTS FOR ELECTRIC LIGHT SOURCES, IN GENERAL). As a US Corporation, Sylvan R. Shemitz Designs, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Sylvan sits between Suzhou Luxshare Technology Co., Ltd (11 patents, rank #25,207) and Szegedi Tudományegyetem (11 patents, rank #25,215) - the closest US assignees by grant volume. The composite Innovation Score of 22.0/100 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 1 grants, compared with 10 in the 2015–2019 window, a -90% 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. Sylvan R. Shemitz Designs, Inc.'s 6.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sylvan R. Shemitz Designs, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Sylvan's 11 grants land it in the top 90% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
