It seems that your question may be posed with an Acquirer and Target in mind. There would be no boilerplate answer your question as each and every scenario relative to acquiring a target for R&D would be different. I would offer that a company could define their policy for determining the build or buy decision (build infrastructure or buy) and apply that methodology to each scenario. I’m sure there would be instances where the Acquirer has capable resources and equipment to get the job done and in another instance they may not. Having the business strategy for R&D along with criteria for determining the build/buy decision would then be much easier.
