The U.S. Patent and Appeal Board this week handed down mixed rulings in a pair of important cases involving drug patents.

Why it matters: The patent system is the foundation of drug companies' ability to keep their prices high, and these specific rulings will affect access and cost for two drugs that treat serious conditions — HIV and multiple sclerosis.

Biogen won a patent dispute over its multiple sclerosis drug Tecfidera, which generated $4.4 billion of global revenue in 2019 — meaning a cheaper competitor won't come this year.

  • The Tecfidera patent doesn't expire until 2028, although Biogen expects generics to hit the market before then due to other pending cases.
  • Read the decision.

Gilead failed to invalidate patents held by the federal government pertaining to its HIV prevention pill, Truvada.

Sen. Elizabeth Warren and Hillary Clinton both are slated to speak on the Wednesday of the Democratic convention — Aug. 19 — four sources familiar with the planning told Axios.

Why it matters: That's the same night Joe Biden's running mate (to be revealed next week) will address the nation. Clinton and Warren represent two of the most influential wise-women of Democratic politics with the potential to turn out millions of establishment and progressive voters in November.

Trump considering order on pre-existing condition protections, which already exist

President Trump announced on Friday he will pursue an executive order requiring insurance companies to cover pre-existing conditions, something that is already law.

Why it matters: The Affordable Care Act already requires insurers to cover pre-existing conditions. The Trump administration is currently arguing in a case before the Supreme Court to strike down that very law — including its pre-existing condition protections.
