Patent priority

It is important that the laboratory record reflect the exact stage of each procedure as it is carried out. This is essential when the experimentalist carries out several preparations simultaneously. It is even more important as a means of communication between chemists working on various phases of a single project. After interruptions or emergencies, the record helps in determining how to proceed with the work. The notes should help in detecting causes of unusual observations, as well as causes of accidents or fires. In other words, there are important safety considerations. It cannot be emphasized enough that detailed and accurate notes are essential for patent applications and patent priority claims. 

Total patent priority period equals 20 plus 1 years.

For practicing analytical chemists and on-the-job apphcations, it is especially important to use the lab notebooks for entering observations and measurements directly. Complete documentation is essential for forensic or industrial laboratories for legal or patent considerations. In industrial research labs, the notebook must generally be signed (witnessed) and dated by another person familiar with the work to assure legal patent priority if applicable.

Since pyrethroid research is now, in many aspects, a finished chapter of apphed research, a historical treatment of the course of inventions is given (inventions, patent priorities). 

The reinaining five search topics (Research Topic, Author Name, Document Identifier, Company Namc/Organii ation, and Browse Table of Contents arc conducted in a similar fashion, with the input being the only difference between the criteria. Thus, in Research Topic" the entry can be any, or even several, keywords or phrases. In "Author Name", literature written by a specific author will be Found, including alternative spelling, Document Identifier" can also be entered directly in the query. Document identifiers arc CA abstract numbers, patent numbers, patent application numbers, or priority application numbers. The last two search topics (Company Name/Organi2ation, and Browse Table ofContents) allow one to search for literature from specific companies or to view the list of journals which are available in the database. 

By the turn of the century the U.S. PTO may be operating under a system that includes (/) pubHcation of patent appHcations (2) opposition of allowed appHcations for purposes of testing vaHdity (J) the dawn of first-to-file priority examination and (4) the end of the antiquated test of inventorship called "interference practice." Legislation implementing many of these changes is pending before the U.S. Congress.

As noted in Chapter 1, the priorities in batch processes are often quite different from those in large-scale continuous processes. Particularly when manufacturing specialty chemicals, the shortest time possible to get a new product to market is often the biggest priority (accepting that the product must meet the specifications and regulations demanded and the process must meet the required safety and environmental standards). This is particularly true if the product is protected by patent. The period over which the product is protected by patent must be exploited to its full. This means that product development, testing, pilot plant work, process design and construction should be fast tracked and carried out as much as possible in parallel.
