Fortem IP provides sophisticated legal counsel at competitive rates to clients ranging from emerging companies to international corporations. We specialize in patent prosecution and counseling, commercial transactions, and trademark registration and enforcement.

Our fees are based on an hourly or fixed fee structure. We work with our clients to determine the most appropriate fee arrangement. Our patent and trademark prosecutions services are primarily offered on a flat-fee basis. Our project-based business model eliminates the inefficiencies of time-based billing, allowing us to devote more time towards gaining a deeper understanding of our client’s business. In flat-fee engagements, we do not bill clients for meetings, emails, and phone calls. Instead we collaborate with our clients, leveraging our expertise to build a legal strategy around their technology and business vision.
