What changed
MICROPHYT filed a patent application for a method of using hydrolysate from P. tricornutum microalgae extraction coproducts in cosmetic formulations. The claimed uses include skin exfoliation and reduction of skin microrelief. The application identifies three inventors (Cyrielle Houdin, Rémi Pradelles, Clémence Thebaud) and was originally filed as Application No. 19111182 on September 20, 2023.
Patent applications do not create immediate compliance obligations for the cosmetics industry. However, manufacturers developing similar microalgae-based exfoliant or skincare products should review the claims to assess potential freedom-to-operate concerns or opportunities for licensing. This publication represents an early-stage intellectual property filing; the claims may narrow significantly during examination.
