Contact The History of the Folding Bike There have been many who have laid claim to the invention of the folding bike. Humorously, a bike manufacturer who shall remain nameless so as to not unduly embarrass them audaciously claims on their website to have produced the world’s first folding bike in Wishful thinking by their marketing department I suppose. The truth is that the folding bike has been around for considerably longer than one might imagine and most claims of being the first are erroneous. First things first though, you can’t have a folding bike without the invention of the bicycle itself. So a very short history lesson on the bicycle is in order. Here again we have some disputed claims of invention and historians will probably never be able to identify the exact moment of invention.

Brief History: American Waltham Watch Company

Case serial number The Online Database for the Elgin Watch Company can tell you a great deal of information about your watch, based on just the serial number off the movement. The “movement” is also sometimes called the “watch works”. Serial Number off the movement:

patent numbers and dates If you have ever had trouble dating old instruments, this list may be a help. It shows the first patent number issued in each year, so if you have a patent number, this easily yields the approximate date to begin with.

Those three date ranges are differentiated by the presence or absence of certain case and movement markings as well as the nature of any such markings, as explained below. In general, for all time periods, it is important to understand that Bulova watches never provide an obvious date of manufacture anywhere on the watch. Rather, the date must be “de-coded” using symbols, serial numbers, and two-character codes placed on various parts of the watch.

These codes and the manner in which they should be interpreted is the subject of this article. Many observers of Bulova watches are confused by the sometimes seen patent dates stamped on the inside of some Bulova watch cases, and they misinterpret such dates as the time of manufacture. In point of fact, those patent dates apply only to certain aspects of the case design and indicate only when those general designs were patented.

Those designs were used on many watches produced over a number of years, and the applicable patent date in no way indicates when any particular watch was produced. Below are images showing the two patent dates that often cause confusion.

This morning the Supreme Court released it’s opinion in Microsoft v. Section requires an invalidity defense to be proved by clear and convincing evidence. Radio Engineering Laboratories, Inc. The Court also rejected the argument that a preponderance standard must at least apply where the evidence before the fact finder was not before the PTO during the examination process. But the question remains whether Congress has specified the applicable standard of proof.

As established here today, Congress did just that by codifying the common-law presumption of patent validity and, implicitly, the heightened standard of proof attached to it. And they do not indicate, even in dicta, that anything less than a clear-and-convincing standard would ever apply to an invalidity defense. In fact, the Court indicated to the contrary. However, while not endorsing any particular methodology, the Court did note that unconsidered evidence may be given more weight during trial via jury instructions: Simply put, if the PTO did not have all material facts before it, its considered judgment may lose significant force.

In this respect, although we have no occasion to endorse any particular formulation, we note that a jury instruction on the effect of new evidence can, and when requested, most often should be given. When warranted, the jury may be instructed to consider that it has heard evidence that the PTO had no opportunity to evaluate before granting the patent. When it is disputed whether the evidence presented to the jury differs from that evaluated by the PTO, the jury may be instructed to consider that question.

In either case, the jury may be instructed to evaluate whether the evidence before it is materially new, and if so, to consider that fact when determining whether an invalidity defense has been proved by clear and convincing evidence.
