Portfolio overview

Sennheiser Electronic Gmbh & Co. KG has been granted 152 US utility patents between 2015 and 2024, placing Sennheiser Electronic Gmbh & Co. KG at rank #2,567 across all assignees tracked by PlainPatent. This portfolio spans 33 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.5 claims per patent with primary concentration in H04R (LOUDSPEAKERS, MICROPHONES, GRAMOPHONE PICK-UPS OR LIKE ACOUSTIC ELECTROMECHANICAL TRANSDUCERS; DEAF-AID SETS; PUBLIC ADDRESS SYSTEMS). As a Foreign Corporation, Sennheiser Electronic Gmbh & Co. KG is one of the more focused assignees in the PatentsView dataset. By volume, Sennheiser sits between Nanotek Instruments Group, Llc (152 patents, rank #2,563) and AMS Sensors Singapore PTE. Ltd. (151 patents, rank #2,571) - the closest US assignees by grant volume. The composite Innovation Score of 47.5/100 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 55 grants, compared with 97 in the 2015–2019 window, a -43% 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. Sennheiser Electronic Gmbh & Co. KG's 10.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 33 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sennheiser Electronic Gmbh & Co. KG against peers pursuing similar technology classes.

How to use this portfolio

Sennheiser's 152 grants land it in the top 18% 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 - Sennheiser ranks #2,567 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H04R - see who else leads that technology area. H04R 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.
