The first step to file internationally for a US inventor is often a PCT application to access countries that are part of the PCT convention within 30 or 31 months (for most countries) of the earliest priority date.  Other countries that are not part of this convention are accessible within 12 months of the earlier priority date.  We can help you prepare and file a PCT application, as a first application or claiming priority to an earlier application filing within 12 months.  We help you select a receiving office and an international searching authority.

Once your PCT is filed, we work with local law firms ("foreign associates") to file national phase applications in the desired PCT convention member countries.  We can also file within 12 months of the priority application under Paris Convention for those applicants from non-PCT countries. 

If the International Search Report and Written Opinion are favorable and the patent prosecution highway (PCT-PPH) is available or if the same claims have been allowed by the USPTO or another country's patent office that has with a bilateral or multilateral treaty (Global PPH or IP5 PPH) with the desired country's patent office, the PPH can be used for quicker service.  The local patent offices do not have to follow or agree with the Written Opinion or other patent office. 

You can find an example listing of patent applications that Mr. Silver worked on at our patent listing page and client reviews on our patent page.  Did you know that we have a Request for Proposal (RFP) form that you can fill out to get a quick price quote?

Mr. Silver began his legal career at an intellectual property boutique law firm that handled a large volume of  international work.  Here, he regularly helped convert PCT applications into US national stage patent applications and prosecute such cases to allowance (results cannot be guaranteed).  These US applications can be in the form of regular applications, patent prosecution highway accelerated examination, or some other form of accelerated examination. 


With foreign patent attorneys or foreign law firm associates, silverlegal is open to different relationships whether driving the analysis and recommendations or reviewing their strategies. 


Translations are a significant component and cost of national phase applications.  We can request the foreign associates to create the translations of the specifications and references, or we can use other available translation services.

Unlike at the USPTO, many other countries require you to pay for and request examination.
