My company artiste-qb.net owns 11 USA quantum computing software patents (5 granted, 6 pending). If Cambridge Quantum Computing is infringing on our patents, we would definitely sue them and their main investor Grupo Arcano, which has an office in Miami.
Suing for patent infringement can cost millions of dollars per case. Such high costs put it far out of the reach of a small business like us. But there is a way around this obstacle: hiring patent lawyers on a contingency basis. Nowadays, there is a whole “patent troll” industry of law firms that specialize in suing rich companies for patent infringement, and such firms often offer to work for you on a contingency basis, meaning that you don’t pay them anything. They subtract their fees from the final money settlement.
Quite frankly, if we were to sue Cambridge QC, we would not care if the lawyers got 99% of the settlement money. Our goal would not be to make any sort of profit from the lawsuit but to inflict maximum damage on Cambridge QC.
The following article is a good introduction to this method of patent litigation:
Patent Contingent Fee Litigation, by David Schwartz on March 25, 2012
In the last decade, a substantial market has begun to develop for contingent fee representation in patent litigation. Wiley Rein — a traditional general practice law firm with hundreds of attorneys practicing all areas of law — represented a small company, NTP, Inc., in its patent infringement lawsuit against Research in Motion, the manufacturer of the Blackberry line of devices. The lawsuit famously settled in 2006 for $612.5 million, and the press reported Wiley Rein received over $200 million because it handled the lawsuit on a contingent fee basis. And Wiley Rein is not alone in doing so. Many patent litigators around the country have migrated toward handling patent cases on a contingent fee basis.
