The previously approved European patent for Strangvac is valid until May 2031. With the newly granted supplementary protection in the United Kingdom, along with previous applications in other European markets including Sweden, Benelux, Italy, Ireland, France, Spain, Germany, and Austria, we have high hopes thatthe protection for Strangvac will be extended and valid until May 2036 across Europe. Vaccines typically have a long product lifecycle, and the risk of someone developing a biosimilar to a vaccine once the patent has expired is minimal. In both the EU and the USA, there are specific regulations for approving biosimilars, and none of the more than 130 approved biosimilars relate to a, veterinary or human vaccine.

Supplementary protection, or Supplementary Protection Certificate (SPC), is an intellectual property right that acts as an extension of patent protection. It is specifically designed for pharmaceutical and plant products that are protected by patents and have been approved for sale by the European Commission. This protection aims to compensate the patent holder for the time required to meet extensive regulatory requirements before marketing authorization can be granted.

"We are very pleased to have received this supplementary protection approval in the United Kingdom. It provides us with an important extension of our patent protection in one of our key markets," commented CEO Jonas Sohlman, adding, "We believe that Strangvac will become the leading vaccine against strangles globally and will continue to contribute to improved animal health long after the patent and supplementary protection have expired."
