5. Developing technology without ensuring that the technology does not violate someone elseâ€™s intellectual property rights. There is little that will threaten the survival of a start-up company more than a patent infringement lawsuit filed against it. Patent infringement lawsuits are very expensive, and if a company is found to infringe on someoneâ€™s patent, a court can stop the infringer from selling the infringing product. Companies should put in place a system that includes monitoring issued and pending patents to avoid developing technology that will infringe on a third partyâ€™s patent. That system can be internal, or it can be outsourced to a company or firm that specializes in providing what is typically referred to as â€œclearance opinionsâ€ for developing technology.
