Journal Entries

1. For transactions in 2016 and 2017:

Date	Account Titles and Explanation	Ref. No.	Debit	Credit
2016	Research and Development Expense		$149,760
	Cash			$149,760
	(To record research and development expense)
2016	Patent		$23,760
	Cash			$23,760
	(To record cost of patent/legal expenses)
2016	Amortization Expense – Patent		$594
	Patent			$594
	(To record amortization expense; 23,760/10 x 3/12 = $1,026)
2017	Amortization Expense – Patent		$2,376
	Patent			$2,376
	(To record amortization expense; 23,760/10 = $2,376)

2. Journal entries for transactions in 2018 and 2019:

Date	Account Titles and Explanation	Ref. No.	Debit	Credit
2018	Patents		$9,000
	Cash			$9,000
	(To record patents)
2018	Amortization Expense – Patents		$2,390
	Patents			$2,390
	(To record amortization expense)
2019	Amortization Expense – Patents		$2,400
	Patents			$2,400
	(To record patents)

Computations:

Patent amortization –

For 2018 Jan 1 – June 1 (5 months) = 23,760/10 x 5/12 = $990

Book value up to June 1 = 23,760 – (594 + 2,376 + 990) = $19,800

Add: infringement cost = $9,000

Book value, patents June 1 = $28,800

Patent amortization June 1- Dec 31 (7 months) = 28,800/12 x 7/12 = $1,400

Total amortization expense, 2018 = 990 +1,400 = $2,390

Book value Jan 1, 2019 = 28,800 – 1,400 = 27,400

• 2019 patent amortization expense = 28,800/12 = $2,400

3. Journal entries for 2020 and 2021:

Date	Account Titles and Explanation	Ref. No.	Debit	Credit
2020	Amortization Expense – Patents		$12,500
	Patents			$12,500
	(To record amortization expense)
2021	Amortization Expense – Patents		$12,500
	Patents			$12,500
	(To record amortization expense)

Computations:

For 2020 book value -

28,800 – 1,400 – 2,400 = $25,000

Since the patent is determined to become obsolete by December 31, 2021, the entire book value would be written down in the two years, 2020 and 2021, respectively.
