What Ohlandt, Greeley & Perle, LLP does

Ohlandt, Greeley & Perle, LLP (OG&P) is a Stamford, Connecticut–based intellectual property law firm founded by Paul D. Greeley approximately in 1990 and operating continuously for more than 35 years. The firm provides a full-service IP practice across six core disciplines: patent counseling and prosecution, trademark protection and enforcement, copyright registration and licensing, trade secret protection through audits and agreements, IP litigation (including ITC Section 337 investigations, IPR, and PGR proceedings), and transactional IP matters spanning licensing, joint development, and asset/stock purchase agreements. Its attorney bench combines legal credentials with advanced technical backgrounds in chemistry, physics, materials science, chemical engineering, biomedical engineering, biology, and microbiology, enabling prosecution and litigation in life sciences, medical devices, electrical/computer, mechanical, and process-related technologies. The firm does not develop or sell any proprietary software, platform, or technology product; all output is professional legal services delivered as engagement-based work product.

OG&P generates revenue through professional services billing on matter-by-matter engagements initiated by direct client contact via website inquiry or phone. Its client base is horizontally segmented across three primary groups: founders, inventors, artists, and emerging businesses building IP assets; in-house counsel and corporate operators needing external IP coordination; and larger businesses, universities, and multinational corporations with complex global portfolios requiring strategy, enforcement, transactional, and litigation support. Marketing is relationship- and reputation-driven: the firm publishes IP insights on its website, distributes a quarterly newsletter, and leverages speaking engagements at academic institutions (Columbia, Connecticut College, Touro) and bar associations, alongside leadership positions in organizations such as the Connecticut Intellectual Property Law Association and NYIPLA. The firm is privately held as a Connecticut LLP under founder and Managing Partner Paul D. Greeley, with Partners and Counsel including David Aker, Michael S. Bartolone, Stephen A. Latuso, Jerry L. Coon, and Andrea L. Hemberger, and no external equity, parent entity, or institutional investment identified in available materials.
