More About Us

More About Us

PPG serves universities and research institutions, life sciences companies, cutting-edge startups, and the investors backing them. We think like business partners because IP decisions are business decisions. 3,000+ patents secured across 73 countries.

From antibodies and peptides to drug delivery, biomaterials, polymer chemistry, and beyond. PPG’s knowledge spans the full spectrum of life sciences and chemical innovation. Whatever your technology, we already speak science.

Technology Areas We Serve

Technology Areas We Serve

Founded in 2004 after departing a 1,000+-lawyer international firm, PPG was built on one insight: complex IP deserves specialists, not generalists. You get partner-led work, direct access, and a team that is 100% focused on IP because that is all we do.

Not just smart. Strategic.

We understand the science behind our clients’ discoveries and the business strategies behind their development. That dual knowledge positions PPG to find approaches others don’t see.

We don’t settle. We fight.

When an examiner says no, we know how to push back. When claim scope can be maximized, we push further. When our clients need to go to appeal, we win. Our allowance rate is 12 pp higher than the USPTO average, and our patent appeals win rate is 5 pp higher.

Relationships are the foundation of all we do.

Over 95% of our original clients followed us when we launched. That kind of trust doesn’t come from a firm name. It comes from the people behind it. We build long-term partnerships grounded in direct access, genuine investment, and goals that are fully aligned with yours.

A Focus on Research.

From prestigious universities to independent research centers, PPG has spent two decades turning academic discovery into commercially enforceable IP. We understand the timelines, the stakeholders, and the science because we've done it hundreds of times.

Built for the complexity of established science.

Large pharma, biotech, and chemical companies need a team that can move fast, think strategically, and handle technically demanding portfolios without losing depth. PPG's PhD-heavy team works at the intersection of science and commercial strategy, the way in-house counsel needs outside counsel to work.

Diverse Leadership. Deeper Perspective.

60% of PPG's partners are women or minorities, well above the industry average. We've built a firm that reflects the breadth of the scientific community we serve, because diverse teams ask better questions, challenge assumptions, and build stronger IP
