Kurin, Inc.

Kurin, Inc. is a privately held, certified minority-owned medical device company headquartered in San Diego, California, founded in 2015. The company has approximately 79 employees and has reported strong revenue growth, including record revenues for Q1 2026.

Kurin specializes in developing and manufacturing blood culture collection sets designed to reduce contamination and improve diagnostic accuracy. Its primary product lines include the Kurin Lock® family and Kurin Jet™ blood culture collection sets, which passively divert an initial small volume of blood (approximately 0.15 mL) to sideline skin-derived contaminants during venipuncture or peripheral IV draws. This technology aims to prevent false-positive blood cultures, reduce unnecessary antibiotic use, decrease hospital costs, and enhance patient safety. Kurin also offers the Kurin Advance™ push-button safety needle.

As an operating company, Kurin, Inc. is involved in patent litigation primarily as a defendant, defending its innovations and fending off infringement claims. The company has one tracked case where it appears as a defendant before the Patent Trial and Appeal Board (PTAB) in Unified Patents v. Kurin, Inc. This indicates a challenge to one of Kurin's patents by Unified Patents, an organization known for contesting patent validity.

Kurin has also been notably involved in extensive patent litigation with competitor Magnolia Medical Technologies, Inc. In this context, Kurin has successfully defended itself against Magnolia's allegations of patent infringement regarding its Kurin Lock product. The U.S. Court of Appeals for the Federal Circuit recently affirmed decisions in Kurin's favor, ruling that its product did not infringe Magnolia Medical's patents. Additionally, a PTAB decision in May 2026, Magnolia Medical Technologies, Inc. v. Kurin, Inc., denied institution of an inter partes review petition against a Kurin patent, reinforcing the view that PTAB challenges should serve as an "alternative to litigation" rather than a re-litigation of previously decided issues.
