Abstract From the Canadian patent

The invention provides methods and kits for producing specific binding pairs (sbp) members. Populations of polypeptide chain components of sbp members are combined to form libraries of sbps displayed by secreted replicable genetic display packages (rgdp). At least one of the polypeptide chains is expressed as a fusion with a component of an rgdp which thereby displays that polypeptide chain at the surface of rgdp. At least one population of polypeptide chains is expressed from nucleic acid which is capable of being packaged using a component of an rgdp whereby the genetic , material of rgdps produced encodes a polypeptide chain. The methods enable production of libraries of multimeric …

Why it's free to use

  • Filed May 15, 1992 and granted October 1, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 15, 2012.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 15, 2014.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
