On January 2, 2018, David Corporation purchased a patent for $400,000. The remaining legal life is 12 years, but the company estimated that the patent will be useful only for eight years. In January 2020, the company incurred legal fees of $30,000 in successfully defending a patent infringement suit. The successful defense did not change the company's estimate of useful life.
