Our Company

At Billtrader we hate the phrase "it's just business". For us, business is personal.


In 1969 Computer Patent Annuities was founded by a group of patent attorneys who sought a better solution for paying patent annuities. Today CPA Global is a billion-dollar company and the largest IP services company in the world.

Billtrader has a similar DNA - sick of paying tens of thousands of dollars a year in fees to wire funds to their patent colleagues around the globe, a group of patent attorneys got together to figure out a better solution. That solution was Billtrader.

To date we've received $4.2 million of investment from over 50 patent attorneys from seven of the world’s top patent firms across four continents. With such broad support for the Billtrader concept we have great confidence in the future of the business.
