We capitalize external costs, consisting primarily of legal costs, related to securing our patents and trademarks. Once a patent is granted, we amortize the approved hormone therapy drug candidate patents using the straight line method over the estimated useful life of approximately 20 years, which is the life of intellectual property patents. If the patent is not granted, we write-off any capitalized patent costs at that time. Trademarks are perpetual and are not amortized. During the three months ended March 31, 2018 and year ended December 31, 2017, there was no impairment recognized related to intangible assets.

We have numerous pending foreign and domestic patent applications. As of March 31, 2018, we had 16 issued foreign patents and 18 issued domestic, or U.S., patents including:

●

13 domestic utility patents that relate to our combination progesterone and estradiol product candidates, which are owned by us. These domestic utility patents will expire in 2032. In addition, we have pending patent applications with respect to our combination progesterone and estradiol product candidates in the U.S., Argentina, Australia, Brazil, Canada, Europe, Israel, Japan, Mexico, Russia, South Africa, and South Korea;

●

Three domestic patents that relate to TX-004HR, our applicator-free vaginal estradiol softgel product candidate. These patents establish an important intellectual property foundation for TX-004HR and are owned by us. These domestic patents will expire in 2033 or 2032. In addition, we have pending patent applications related to our applicator-free vaginal estradiol softgel product candidate in the U.S., Argentina, Australia, Brazil, Canada, Europe, Israel, Japan, Mexico, Russia, South Africa, and South Korea;

●

One domestic utility patent that relates to our pipeline transdermal patch technology, which is owned by us. The domestic utility patent will expire in 2032. We have pending patent applications with respect to this technology in the U.S., Australia, Brazil, Canada, Europe, Mexico, Japan, and South Africa; and

●

One utility patent that relates to our OPERA^® information-technology platform, which is owned by us and is a domestic patent that will expire in 2029.
