Accounting for Patents On January 3, 2005, Merris Company spent $89,000 to apply for and obtain a patent on a newly developed product. The patent had an estimated useful life of 10 years. At the beginning of 2009, the company spent $16,000 in successfully prosecuting an attempted infringement of the patent. At the beginning of 2010, the company purchased for $37,000 a patent that was expected to prolong the life of its original patent by five years. On July 1, 2013, a competitor obtained rights to a patent that made the company's patent obsolete.
