For intangible assets with finite lives, a company uses the straight$-$line method to calculate amortization. If a company successfully defends a patent it becomes part of the cost of the patent. If the company loses a lawsuit regarding a patent infringement, then the patent is written off.

b$.$ Journalize the adjusting entry on December $31$ of Year $4$ to recognize the amortization. If an amount box does not require an entry, leave it blank.
