If you want your views to be known, we now open this monthly review to columnists, bloggersand IP practitioners. Send us an email at [email protected] and lets discuss how we canwork together. We also accept advertorial and advertisement placements.
Structure of this review
The Table of Contents is created based onalphabetical order of IPC. The patent applicationsare also sorted by alphabetical order of IPC. A briefdescription of each IPC is shown. We find that the IPCdescription could help ‘deciphering’ the abstract of anpatent application. If a patent application belongs tomultiple IPC, the patent application will only be shownunder the section of first IPC.For each patent application, the following informationwill be shown:
1. App. No. – patent application no. – it is uniqueto each patent application.
2. Assignee – this is owner of the patentapplication. If there is no assignee beingspecified, either the inventor of the patentapplication own the patent application or theowner of the patent application did not recordsuch information when the patent applicationwas filed.
3. Title – this is the title of the patent application.
4. Abstract – this is the abstract of the patentapplication. There are rules on how an abstractshould be drafted. Most patent attorneys like tohave the abstract based on the first claim of thepatent application.
5. Pri. Date – priority date – it is the dateof filing of the first application of the patentapplication (a patent application could havemultiple application dates because of divisionalpatents as well as overseas patent applications).It is considered to be the effective date of filingfor the examination of novelty and inventivestep or non-obviousness for the subsequentapplication claiming the priority of the firstapplication.
6. App. Date – application date – it is the date offiling of the patent application at the US.
7. Pub. Date – publishing date – it is the date of thepatent application published by US. Usually, it isabout 18 months after the application date.
