Portfolio overview

ARK Crystal, Llc has been granted 10 US utility patents between 2017 and 2024, placing ARK Crystal, Llc at rank #25,708 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.8 claims per patent with primary concentration in C30B (SINGLE-CRYSTAL GROWTH ; UNIDIRECTIONAL SOLIDIFICATION OF EUTECTIC MATERIAL OR UNIDIRECTIONAL DEMIXING OF EUTECTOID MATERIAL; REFINING BY ZONE-MELTING OF MATERIAL ; PRODUCTION OF A HOMOGENEOUS POLYCRYS). As a US Corporation, ARK Crystal, Llc is one of the more focused assignees in the PatentsView dataset. By volume, ARK sits between Areva Stockage D'energie (10 patents, rank #25,704) and AS Strömungstechnik Gmbh (10 patents, rank #25,712) - the closest US assignees by grant volume. The composite Innovation Score of 29.2/100 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 6 grants, compared with 4 in the 2015–2019 window, a +50% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. ARK Crystal, Llc's 11.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ARK Crystal, Llc against peers pursuing similar technology classes.
