At the outset, Arlene Chow frames patent litigation matters from the perspective of the judge or jury in order to achieve the best solutions for her clients.

Leveraging her biochemistry experience, Arlene is one of only a handful of lawyers who has been first-chair in district court trials and hearings, federal circuit arguments, and inter partes review hearings before the United States Patent and Trademark Office (USPTO). Arlene is a USPTO-registered patent attorney. She also performs patent due diligence in support of the purchase or sale of drugs or their royalty streams.

Arlene dives deeply into the relevant science and underlying facts before extracting key case themes for development with the case record. She thrives on engaging with in-house and external experts on the science and simplifying the highly technical information in a way that is easy for her clients to digest.

Arlene primarily focuses on life sciences, having worked on matters implicating small molecule and biologic drugs for the treatment of indications, including ulcers; depression; schizophrenia; pneumonia; hemophilia; pain; menopause; anaphylaxis; glaucoma; multiple sclerosis; hypertension; diabetes; COPD; overactive bladder; asthma; overactive thyroid; arthritis; irritable bowel; urinary tract infections; hepatitis; and skin, lung, and prostate cancer. Arlene has also handled matters involving a wide variety of medical devices and dosage forms, including auto-injectors, orally disintegrating and buccal tablets, transdermal patches, spinal devices, sprays, gels, inhalers, gastric bands, and nebulizers.
