Sperry turned his attention to the American Can Company s huge amount of scrap metal remaining after round can tops were pressed from square sheets. He and his colleagues refined American Can s electrolytic detmning process to deal with this scrap so that absolutely pure tin powder resulted. In 1907 and 1908, Speriy was involved m patent interference cases concerning this detiiiiiiiig process. The outcome was that... 

In addition to the mandatory maintenance fees, there are certain postgrant procedures that can take place under special circumstances. For example, patent interferences occur where a contest is waged in the USPTO to determine the first inventor of contested subject matter. These contests may occur between two or more applicants... 

If a long time occurs between an actual reduction to practice (meaning the completion of the invention) and the filing of a patent application, then the concept of due diligence is not in play but rather the question becomes one of whether the inventor abandoned, suppressed, or concealed the invention. This possibility is covered separately by 102(c), which pertains to the abandonment of the invention and, more important, by 102(g) where, in a contest to prove who had invented the subject matter first (patent interference), a party found to have abandoned, suppressed, or concealed the invention can lose to a later-inventing party who did not commit one of those sins. More on these two sections later in this chapter. 

Patent Office Rule 222 provides for amendment of preliminary statements. However, this procedure is no substitute for careful preparation. One should not give up the search for earlier dates and records but should consider the Patent Office Board of Patent Interferences recent decision (12) denying a motion to amend because of no showing that a proper degree of effort and care was exercised in preparing the original statement. 

While the above-mentioned estimates assume that the patenting process is rather straightforward, considerable expenses must be anticipated if an opposition has been filed, or if an interference is to be expected in the USA. Due to the complicated procedure, especially of a US patent interference, several ten or hundred thousand dollars are spent readily and the entire cost of an interference procedure may well... 

The need to defend paper examples arises rarely because few patents interfere with other grants. According to the U.S. Patent and Trade Office, about... 

These services bring two advantages to a chemist who avails herself of them. First, they allow her to do other synthetic work in the meantime, accelerating her progress. Second, an analytical chemist who records, say, a proton nuclear magnetic resonance (pmr) spectrum provides evidence independent of the synthetic chemist s say-so. Such a measurement shows the latter scientist had made a certain target or intermediate compoimd by the date on which the spectrum was recorded. This evidence can be valuable during a patent interference. 

This competition also led to an unprecedented international patent race, which has produced more than 1000 patent applications, and several patent interferences with narrow differences in priority dates. 

It is not surprising, given the concurrent research and commercialization efforts that were focused on bringing BPA-based polycarbonates to the market in the late 1950s, that a patent interference arose. Bayer was eventually awarded the first U.S. patents on BPA-based polycarbonates [35] and for the interfacial method of production. GE was issued a patent covering the melt transesterification production process [36]. 

A patent interference is a procedure conducted before the United States Patent and Trademark Office to determine which of two or more parties is entitled to a US patent. When two or more patent... 

The employer of the chemist also has an interest in the individual s notebook. To a large extent the employer s technical know-how is to be found there. Patenting a product or process may depend on the dates found in a notebook. Priority claims in a patent interference case may require an examination of notebooks. Therefore, dates, signatures, and witnesses to the work must be carefully recorded. These are some of the reasons for maintaining and protecting notebooks.
