NEW YORK (TheStreet) -- Shares of Teva Pharmaceuticals (TEVA) - Get Report were falling 5.24 to $50.41 in late-afternoon trading on Wednesday after the U.S. Patent Office's Patent Trial and Appeal Board said that certain aspects of its multiple sclerosis drug Copaxone's patent are invalid.
Bernstein expects that the rest of the patents supporting Copaxone will ultimately be invalidated as well, according to CNBC.
Teva is an Israeli pharmaceutical company.
Separately, TheStreet Ratings team rates the stock as a "buy" with a ratings score of B.
Teva's strengths such as its revenue growth, largely solid financial position with reasonable debt levels by most measures and expanding profit margin outweigh the fact that the company has had lackluster performance in the stock itself.
