专利数据案例研究1——关于临时申请的问题

（1）最近在分析专利数据的时候发现了一些比较诡异的现象，仔细研究之后发现了问题来源于临时优先权问题，所以做了记录，以便后续学习归纳。

（2）具体的案例是US2003104318A1，用这个公开号在DII上检索，会出现两条记录。

（3）起初这个让我百思不得其解。因为,DERWENT的的两条记录的入藏号是有区别，分别为2003-616623，2003-441023，而且，这两条记录虽标题，专利权人相同，但其他如引文、NOVERLTY、USE等信息均不同。这种情况与我们通常认知的DERWENT专利家族_Commercial novelty-based families（这里不详细解释）定义存在一定的出入。

当仔细比较两条记录的差异时，在更多专利详细信息中发现了一些线索，提示US2003104318-A1 Provisional

Application US322408P

（4）于是查阅US2003104318-A1原始文档发现，果然，在图1左下角，Related U.S application Data中指明该专利是存在临时申请的，而且时间是2001年9月14日。

（5）接下来，想继续查找该临时优先权原始信息，发现一些困难，原来，临时优先权通常是不公开的，这在一些特例的情况下公开，但仍是可以尝试找到，未来将试一下。

Provisional Patent Applications Are Not Published

Provisional patent applications are not published since they are not examined and they are only pending at the U.S. Patent Office for 12-months.  After 12-months, a provisional patent application automatically becomes abandoned and therefore will never be published.  Only a non-provisional patent application can be published by the U.S. Patent Office.  Hence, a provisional patent application will remain secret at the U.S. Patent Office with a few exceptions discussed below.

 

Exceptions to Provisional Patent Application Secrecy

While a provisional patent application is never published by the U.S. Patent Office for the public to view or search, there are two situations when a provisional patent application will be made publicly available for inspection.  If a non-provisional patent application is filed claiming priority to the provisional patent application and the non-provisional patent application is either (i) published or (ii) granted as a patent, then the public may download a copy of the provisional patent application via Public PAIR or request a copy of the provisional patent application.  It is important to note that this is not publication of the provisional patent application and the provisional patent application cannot be publicly searched - the only access is provided by Public PAIR or a direct request from the public to inspect the provisional at the U.S. Patent Office.
