Portfolio overview

DEHN + SÖHNE GMBH + CO. KG has been granted 23 US utility patents between 2015 and 2020, placing DEHN + SÖHNE GMBH + CO. KG at rank #12,890 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.5 claims per patent with primary concentration in H01T (SPARK GAPS; OVERVOLTAGE ARRESTERS USING SPARK GAPS; SPARKING PLUGS; CORONA DEVICES; GENERATING IONS TO BE INTRODUCED INTO NON-ENCLOSED GASES). As a Foreign Corporation, DEHN + SÖHNE GMBH + CO. KG is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 29.4/100 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 22 in the 2015–2019 window — a -95% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign 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. DEHN + SÖHNE GMBH + CO. KG's 9.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark DEHN + SÖHNE GMBH + CO. KG against peers pursuing similar technology classes.
