Portfolio overview

Siempelkamp Maschinen- Und Anlagenbau Gmbh has been granted 19 US utility patents between 2015 and 2025, placing Siempelkamp Maschinen- Und Anlagenbau Gmbh at rank #15,641 across all assignees tracked by PlainPatent. This portfolio spans 23 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.4 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 Foreign Corporation, Siempelkamp Maschinen- Und Anlagenbau Gmbh is one of the more focused assignees in the PatentsView dataset. By volume, Siempelkamp sits between Shenzhen Dongjilian Medical Tech Co., Ltd (19 patents, rank #15,637) and Skytap (19 patents, rank #15,645) - the closest US assignees by grant volume. The composite Innovation Score of 47.0/100 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 14 grants, compared with 5 in the 2015–2019 window, a +180% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Siempelkamp Maschinen- Und Anlagenbau Gmbh's 13.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 23 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Siempelkamp Maschinen- Und Anlagenbau Gmbh against peers pursuing similar technology classes.

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.
