Callan Pharma Services offers a unique integration of drug formulation know-how and IP strategy. We don’t just develop formulations; we protect them and ensure your innovation stays yours.
Our Founders Understand Pharmaceutical Intellectual Property
Our founders, Dr. Sill and Dr. Sullivan, recognized early in their careers that a pharmaceutical formulation is only as good as its intellectual property protection—both are registered United States Patent and Trademark Office Agents with a proven track record of developing and protecting innovations in the pharmaceutical industry.
IP White-Space Analysis
White-space analysis identifies unmet formulation and technology gaps across the pharmaceutical landscape, guiding strategic R&D and IP positioning.
Our analysis services help innovators and investors:
- Discover untapped drug delivery and formulation opportunities
- Assess competitive landscapes and innovation hot-spots and gaps
