Only a minority of piano makers have ever published dates of their serial numbers, and many of these are incorrect or misleading, so on this page, I have only included dates for which I have some evidence. If you open the top of a piano and peer inside, you will often find one or more numbers in there. Sometimes, they are harder to see, and may be underneath a grand, so be aware of the dangers of crawling under there. Removable wooden parts of the case are often imprinted with a number, but this may only be the last 3 digits of serial numbers, which are usually long numbers, at least 5 digits. Remember that any handwritten information is probably not from the factory and could have been added at any time. Numbers preceded by a letter are not usually serial numbers. Some more modern serial number dates for British pianos are listed in date order near the bottom of this page. A growing number of websites offer apparently simple dating of pianos by their serial numbers.
About European Patent Validation
Effects[ edit ] A patent does not give a right to make or use or sell an invention. From an economic and practical standpoint however, a patent is better and perhaps more precisely regarded as conferring upon its proprietor “a right to try to exclude by asserting the patent in court”, for many granted patents turn out to be invalid once their proprietors attempt to assert them in court.
Like any other property right, it may be sold, licensed, mortgaged , assigned or transferred, given away, or simply abandoned.
THE RIFLE. The design of the Lee-Enfield Rifle No.8 was the outcome of much research and trialling immediately after the War. At least two prototypes .
It allows the owner of the patent the patentee to take legal action against others who use his invention without his permission. The right has a maximum life-time of 20 years in most countries, from the date of the patent application. What a patent does not do is give the owner an automatic right to use the invention. How do I get a patent? If they decide your invention is patentable, the patent will be granted usually about four years after you made the application, but sometimes sooner than this.
See below for the procedure. Do I need a patent to use my invention? Whether or not you have a patent, you are free to exploit your invention, although only if no one else already has patent rights to it. However, if you do not have a patent, it can be very hard to stop other people copying your invention. Note, as we have said before, that even if you do have a patent, that does not automatically give you the right to use your invention because others may own rights which prevent or restrict your use.
The potential benefits are significant: The tax reduction could easily outweigh the cost of obtaining the UK patent and potentially have a far greater financial benefit to your business.

Cabot led another voyage to the Americas the following year but nothing was ever heard of his ships again. This effort was rebuffed and later, as the Anglo-Spanish Wars intensified, Elizabeth I gave her blessing to further privateering raids against Spanish ports in the Americas and shipping that was returning across the Atlantic, laden with treasure from the New World. By this time, Spain had become the dominant power in the Americas and was exploring the Pacific Ocean, Portugal had established trading posts and forts from the coasts of Africa and Brazil to China, and France had begun to settle the Saint Lawrence River area, later to become New France.
English overseas possessions In , Elizabeth I granted a patent to Humphrey Gilbert for discovery and overseas exploration. Gilbert did not survive the return journey to England, and was succeeded by his half-brother, Walter Raleigh , who was granted his own patent by Elizabeth in Later that year, Raleigh founded the Roanoke Colony on the coast of present-day North Carolina , but lack of supplies caused the colony to fail.
Tips of Performing Japanese Patent Numbers Search. Japanese patent numbering system is very tricky, and confusion, because application number, laid-open publication number, examination number, and granted patent number are all different for the same Japanese patent application.
University World News or Higher Education Web Publishing does not necessarily endorse, support, sanction, encourage, verify or agree with any comments, opinions or statements or other content provided by readers. US universities remain the most prolific international patent filers among higher education institutions worldwide, accounting for 30 of the top 50 institutions.
Israel has two universities in the top 50, and Australia, China, Denmark and Singapore have one each. America also led the top 15 countries in filing international patent applications, followed by Japan and Germany. First and foremost is the public support for research-intensive universities, dating from the land grant college act under President Abraham Lincoln, which created centres for agricultural technology in universities. For example, the NSF has long provided grants to university-industry partnerships that develop technology.
Importantly, the Bayh-Dole Act of allowed universities to patent inventions arising out of government funding. He quoted NSF statistics indicating that the top US research universities now generate more than a billion dollars a year from royalties on intellectual property. With reference to fields of technology, digital communications remains the field of technology accounting for the largest share 7.
While we measure patents and patenting levels, it is a poor indicator of actual invention and even less of innovation the making available of new products or services.
British Registered Design numbers (1842 to 1944)
If your number is higher, but less than the number for the next year, then your item had it’s design registered during that year. In July the numbering sequence changed as indicated on the chart.

As a leader in the unfolding intellectual, social, political, and economic revolutions of eighteenth and nineteenth century Europe, Britain had a long history of extending formal protection to ideas and products. A textbook example of early industrial capitalism was the nineteenth century British pottery industry.
While the early focus of protection was on technique and product, after , English potters could also register their designs or patterns with the Patent Office and then impress or print the registry designation upon a vessel. Doing so likely served at least two functions. First, it provided the producer with some design protection even though English potters were notorious in their “adaptations” of the patterns of others. Secondly, it served as a positive marketing device to the extent that consumers viewed English pottery as a superior product.
However, these two functions were apparently not overly significant because the vast, vast majority of pottery coming out of England lacked registry designation marking. Nonetheless, when a basal sherd displaying a mark is recovered from an archaeological context, we can establish a reasonable dating floor for the vessel. Keep in mind that the date of design registration provides only a clue to the year the item was actually produced. Note that we are speaking here only of the applied registry mark and not of the design itself.
Given that a design could not be registered if it was produced prior to application submission, the date information tells us only that the vessel bearing the mark was manufactured sometime after the date.

These grants conferred no monopoly but encouraged artisans to settle and transmit their knowledge and know-how to native apprentices. The migration of skilled workers and engineers was the primary channel through which technology was transferred, both within and between countries. As local guilds battled to retain trade secrets exclusively for their members, privileges became weapons in the hands of rivals to lure ambitious or dissatisfied guildsmen and elicit their secrets.

Frequently one finds that sellers guess-timate the age of a piece to show the item in its most favorable light. Weekend collectors–in a post-brunch glow and accompanied by a charming companion–are all too ready to hear the best of an object that has attracted their attention. As we say on the Street: That’s what makes a trade. But my column is about investment in tangibles–not about entertainment.
If you are investing in an object for resale, it is useful to have something more concrete than a distant memory of a hopeful conjecture an enthusiastic dealer made in passing. In , the US Patent Office opened for business. Makers of things great and small have seen fit over the years to obtain patents for their items or processes. The variety of objects patented is extraordinary–everything from machine motors to earring closures.

In , Selden sold his patent to a group of investors who called themselves the Electric Vehicle Company. In turn, they immediately sued the Winton Motor Carriage Company, the largest car manufacturer in the United States, for infringing on the Selden patent just by building gas-powered cars. On the contrary, it could be quite profitable and limit competition in a highly competitive industry. It also drummed up business for its own members by threatening to sue anyone who bought a car from an unlicensed company.
It excluded the Midwestern manufacturers who built lower-priced cars for ordinary people. In particular, it excluded Henry Ford. On October 22, , the ALAM sued Ford for patent infringement, but the case took until , seven months after the Model T was introduced, to go to trial. The court ruled that any gas-powered vehicle unlicensed by the ALAM violated the Selden patent and was illegal. Fact Check We strive for accuracy and fairness.
