Portfolio overview
Guill Tool & Engineering Co., Inc. has been granted 39 US utility patents between 2015 and 2025, placing Guill Tool & Engineering Co., Inc. at rank #8,215 across all assignees tracked by PlainPatent. This portfolio spans 19 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.1 claims per patent with primary concentration in B29C (SHAPING OR JOINING OF PLASTICS; SHAPING OF MATERIAL IN A PLASTIC STATE, NOT OTHERWISE PROVIDED FOR; AFTER-TREATMENT OF THE SHAPED PRODUCTS, e.g. REPAIRING). As a US Corporation, Guill Tool & Engineering Co., Inc. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 36.6/100 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 22 grants, compared with 17 in the 2015–2019 window — a +29% 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. Guill Tool & Engineering Co., Inc.'s 9.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 19 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Guill Tool & Engineering Co., Inc. against peers pursuing similar technology classes.
