Brain v Ingledew Brown Benson and Garrett and Another: CA 1996

The defendant firm of solicitors had acted for a Danish Research Institute. They wrote to several parties regarding a patent. B initiated a threat action. IBB appealed against an order striking out their defence, saying that the issue of whether what they said amounted to a threat was a question of fact to be decided at trial, and not on a summary application.
Held: The appeal succeeded. Until the patent was granted before trial, the defendant could justify his action. Whilst the judge could ascertain the meaning of the letter complained of, whether it amounted to a threat remained a question for the trial.
Aldous LJ said: ‘the conclusion as to whether a document amounts to a threat of patent proceedings is essentially one of fact. It is a jury-type decision to be decided against the appropriate matrix of fact. Thus a letter or a statement may on its face seem innocuous, but when placed in context it could be a threat of proceedings. The contrary is less likely but could happen.’ and ‘even if it be assumed that the letter contained a threat in general terms it does not follow that the recipient would read it as making a threat of proceedings in respect of all potentially infringing acts. A letter, such as the letter of June 13, when written to a person who only operated a process, could be understood as being a threat of infringement by carrying out the process; whereas a letter written in general terms to a person who not only carried out the process but sold the products of that process, could be understood in a different way.’
