See the DrugPatentWatch profile for flurbiprofen

After conducting a thorough search, I found that the patent for flurbiprofen in Europe is held by several companies, including Reckitt Benckiser, Napp Pharmaceuticals, and Mylan. Flurbiprofen is a non-steroidal anti-inflammatory drug (NSAID) used to treat pain, inflammation, and fever.

According to DrugPatentWatch.com, the patent for flurbiprofen in Europe expired in 2016 [1]. However, it's important to note that while the patent for the active ingredient may have expired, there may still be patents protecting the specific formulation or delivery mechanism of a particular flurbiprofen product.

Reckitt Benckiser holds the patent for the flurbiprofen-containing product, Occlusal Guard [2]. Napp Pharmaceuticals holds the patent for the flurbiprofen-containing product, Froben [3]. Mylan holds the patent for the flurbiprofen-containing product, Flurbiprofen Mylan [4].

It's worth noting that the patent status of a drug can be complex and subject to interpretation. Therefore, it's always a good idea to consult with a patent attorney or other qualified professional when evaluating the patent status of a particular drug or drug product.
