When a "patent law office specializing in intellectual property and technology is hired to work on ones technology...who is it that writes the patent "Claims and Description"?
I'm not sure I understand completely. When you hire a patent practitioner or firm, it's generally expected that the hired practitioner/firm will write the application. If you choose to do it yourself, the practitioner/firm can review, edit, and file it for you. Or, you can bypass the practitioner/firm altogether and do it yourself, though it's not generally recommended. In short, you decide who writes your application; it's not decided for you.
Is it an unrealistic dream to expect a monopoly on the technolgy for years to come if it was claimed broad enough and the technology was unique enough? It seems in todays market place there are knock offs everywhere in all corners of IP and Trademarks and as a small company with limited resorces it would be devastating if a large corporation was your first litigation case.
Even the most cash-flush companies don't really file their patent applications in every country in the world. I have yet to see a situation in which complete coverage in 100% of the world was economically justified. Pharmaceuticals might be one exception, but I really don't know where such companies file. And, you can exhaust a moderate budget with just a few foreign applications.
If your product becomes popular, you can readily expect knock-offs. In theory, you can stop the knock-offs at the border. However, while Congress has budgeted money for increased port security and increased container inspections for national security, the executive branch hasn't done anything with those funds for three straight years. I was hoping that an unintended consequence of such increased port security would result in tighter policing of knock-offs entering the country. Alas, that increased security never arrived and neither did any unintended consequences.
And, you should expect that litigation may be necessary if your invention really is a "Holy Grail". I hope I'm not destroying anyone's illusions of the marketplace, but business people can be downright nasty. Be prepared to have bigger companies blatantly infringe any patents you might have if they don't think you have the resources to litigate. Some companies will try to obscure exactly what company is making the knock-offs. People cheat. Yes, they really do! ;-)
So, in conclusion, I think no one should count on a 100% perfect world-wide monopoly on any invention. You may achieve it, but you should never expect it. But, if your idea really is a "Holy Grail," 70% or even 50% of the worldwide market should make a comfortable life for you and your company.
I hope that helps.
