If I find such a patent, should I disclose it ? And even if there is
none known as of today, what is the guarantee there won't be one
published tomorrow ? In which case the patent holder may well seek
retribution from a booming business. Among the companies/organisations
there will be those who can afford to pay anyway, and those who can't
and will have to abandon the technology and still being threatened for
having used it in the past, and leave the market to those who can

What are the guarantees that this cannot happen ? Is the MPEG, 3GPP
and/or W3C responsible for doing a deep patent search to make sure it
can be declared royalty free ?

Side Note: shouldn't it be a service provided by patent offices anyway ?
