As we have discussed earlier, patent literature is not the most important mode to invalidate a patent. Products that are present in the market (from sometime) also forms a very good prior art for invalidating the patent.
I agree that not many products mention the process/methodology that are used by them internally, leave apart the technical specification available on website (as its not available for all products). Further, it becomes more important in those cases where you believe that the product must be using the technology of as claimed in the patent but you have no proof to prove the assumption.
I am assuming here that the relevant text is not available from the specification of the product as well as not much information is available on Google.
A technique that can be used in such cases to check for some references it to search on slideshare or Youtube. Since Google is not able to provide results from these websites they are always left behind.
Now, why to search in these websites. There are many inventors, R&D people, professors etc. who host their presentations or talks on these websites. If these people are connected with some product they even provide information on the technology that is being used in the product. Thats what we are looking for!!!…
Most importantly this also becomes a very important strategy for infringement analysis or licensing deals or claim charts or patent valuation etc.
