Developed Technology Rights

Developed technology rights represent the amortized cost associated with developed technology, which has been acquired from third parties and which can include the right to develop, use, market, sell and/or offer for sale the product, compounds and intellectual property that we have acquired with respect to products, compounds and/or processes that have been completed. These assets include technologies related to the care and treatment of dogs, cats, horses, cattle, swine, poultry, fish and sheep.

Brands and Tradenames

Brands and tradenames represent the amortized or unamortized cost associated with product name recognition, as the products themselves do not receive patent protection and legal trademark and tradenames. The more significant finite-lived brands are Platinum Performance, Excenel, and Lutalyse and the more significant indefinite-lived brands are the Linco family products and Mastitis. The more significant finite-lived trademarks and tradenames are finite-lived trademarks and tradenames acquired from Abaxis. The more significant components of indefinite-lived trademarks and tradenames are indefinite-lived trademarks and tradenames acquired from SmithKlineBeecham.

In-Process Research and Development

IPR&D assets represent R&D assets that have not yet received regulatory approval in a major market. The majority of these IPR&D assets were acquired in connection with our acquisition of an Irish biologic therapeutics company.

IPR&D assets are required to be classified as indefinite-lived assets until the successful completion or abandonment of the associated R&D effort. Accordingly, during the development period after the date of acquisition, these assets will not be amortized until approval is obtained in a major market, typically either the U.S. or the EU, or in a series of other countries, subject to certain specified conditions and management judgment. At that time, we will determine the useful life of the asset, reclassify the asset out of IPR&D and begin amortization. If the associated R&D effort is abandoned, the related IPR&D assets will be written-off, and we will record an impairment charge.

There can be no certainty that IPR&D assets ultimately will yield a successful product.

Product Rights

Product rights represent product registration and application rights that were acquired from Pfizer in 2014.

C. Amortization

The weighted average life of our total finite-lived intangible assets is approximately 10 years. Total amortization expense for finite-lived intangible assets was $230 million in 2020, $237 million in 2019, and $157 million in 2018.

The annual amortization expense expected for the years 2021 through 2025 is as follows:

(MILLIONS OF DOLLARS)	2021		2022		2023		2024		2025
Amortization expense	$	203	$	191	$	183	$	164	$	149
