Why SpencePC?

Clients choose SpencePC because we do outstanding work for fair compensation. Unlike our competitors, we encourage the use of alternative-fee agreements that more closely align our clients’ interests with the Firm’s interests. As a result, our clients pay only for the value they receive.

Our Philosophy

Our philosophy is simple: be outstanding and offer a unique value proposition. Hourly billing creates the wrong incentive for attorneys to work longer, not smarter. Instead, we encourage alternative-fee arrangements that reward success and efficiency. By doing so, our attorneys remain focused on obtaining the best results for our clients in the most cost-efficient manner.

Our Skills

We are attorneys who specialize in intellectual property and complex litigation. We hold science, engineering, and law degrees from the nation’s top schools. Following our education, each of us received years of additional training from prestigious, top-tier law firms. Our billing model ensures we remain focused on obtaining the best results in the most cost-efficient manner.
