does patent beuro take that into consideration while giving patent to someone who decide to patent method. I mean arent there any directories that only have "weight" to patenting beuro?
Lets day I describe method here in this forum I dont think patenting beuro will take my thread into consideration and cancel the filing process of new patent.
I think you are confusing the legal position with the practical situation.
First, the practical situation. I don't know how patent offices check for prior art. I assume they now consult Google as well as other more traditional sources. You could make it easier for them by ensuring that your post has the relevant words in it - in the title and the body. I don't think Google takes excessive notice of titles. But whatever you do there is a risk that the patent office will search on different keywords.
But, from a legal point of view, even if the patent office fails to find your work that does not invalidate it as "prior art" and you could make a claim to invalidate the patent - although I don't believe you could get the patent transferred to you. Note, also, that if another company became aware of your "prior art" they would also be entitled to challenge the validity of the patent - so that they would not have to pay royalties to the company that got the patent.
And let me repeat. I have no legal qualifications.
And, what @westfw said is also important. People with money for expensive lawyers can overwhelm us poorer folk even when their case is very weak.
PS... There is always the option of applying for a patent and then not pursuing the application. That will establish the existence of "prior art"
