Hello, Power Handling,
I have been working as a Patent Attorney for almost twenty years, and can assist you in your posted project. I am presently an independent freelancer working full-time in Freelance. I am registered with the U.S. Patent Office, and have submitted over one hundred patent applications to date.
However, as you may know, a patent practitioner registered in the U.S., for example, cannot "file" an application in another country, unless he is also registered to practice in that country. The usual procedure is to contact a registered agent in Canada, Taiwan, Hong Kong, for example, and have the local practitioner handle the filing. The U.S. practitioner can assist the local practitioner in responding to the local Patent Office, but the correspondence must be handled through the local agent.
Filing in Canada, or Taiwan, or Hong Kong would thus involve contacting a respective Canadian agent, or Taiwanese agent, or Hong Kong agent, and providing the requisite information and documentation to the agent. This effort would take about two hours' of billable time for each country.
Information on the accelerated exam in Canada would be provided by the Canadian agent. Filing an application in Taiwan and Hong Kong may also incur the expense of translating the patent application into Chinese.
Filing a PCT application can be done by a U.S.-based practitioner. The PCT application can be filed online, to save costs. Like many patent practitioners, I have the appropriate "PCT-safe" software and digital certificate loaded on two of my computers. The PCT filing procedure would probably require about three hours' of time to prepare the documentation and complete the on-line submittals. I can work with you to stay within your budget.
