Sorry, but that patent is long gone.

Your husband failed to pay the 3rd maintenance fee, so it expired in July 2004. Even if he would have paid it, it would be expired about 11 years ago.

No.

You cannot patent mathematical concepts. But you can patent a machine that relies on your particular primality test, or related products or methods.

I love answering questions here, but this is really something that you need to have a patent attorney take a look at.

You need to find a manufacturer that will make what you need.

Yes, it can be as simple as that. However, those are not eyelet holes, meaning that those holes have any function except for an ornamental function. These holes are not designed to hold a drawstring or whatever.

This is a very common question. A couple of points:

(1) What the patent covers and does not cover is defined by the claims. Those are the numbered paragraphs at the end of the patent.

The paragraph that you've copied sounds like it was under the heading Field of Invention,... View More

The good news is that if the patent is really expired, then you do not need to purchase the patent. Any that is in the patent is free for anyone to use for any purpose.

That is actually the whole idea behind patents: after the patent expires, anyone can use it.

Firstly, you need to find out if you qualify to sit for the patent bar. Do you at least a BS from some hard-core science or engineering? You need to take a look through the USPTO website, which will guide you through the process.

But to answer your question, there are a number of courses... View More

Congratulations on passing a state bar, Naz!

Although I can't offer you a job right now, here are a couple of points:

(1) You need to decide if you want to go into patent prosecution or patent litigation. Those are two separate practices. Although there are attorneys who... View More

Well, theoretically after the State Street decision such a patent should be possible. However, for several reasons, it will be difficult.

The biggest concern that I'd worry about in your position is what are you going to do with the patent after you get it? Do you have a bank? You... View More

There likely are some patents on this. The easiest way to determine this is to obtain one of these micrometers and look for a patent mark. Alternatively, you may want to discuss your question fully with a patent attorney to get you the advise that you require.

The price for drafting and filing a utility patent varies widely, but about $7,000 to $12,000 seems like a good ball park figure.

You should look for a patent marking on the product or packaging that the product comes in. Although there is no legal requirement to put patent marking on products, a manufacturer that has so many patents would typically mark the product in order to take advantage of the notice requirement....

You have good observation skills.

An applicant can have has as many claims in the patent application as is desired. I've seen patents and patent applications with just one or two claims, but I've also seen patents with hundreds of claims. Typically, a patent has one or more... View More

I do not know, but it is almost guaranteed that any company that supplies its products around the globe would have some sort of a protection on its products. Please do not copy it for your line of beverages without checking with your intellectual property attorney.

Sorry, but you cannot patent a mere idea. You need to have an actual invention.

Once you do have the invention (see your patent attorney what the difference between an invention and a mere idea is), then you need to figure out how you are going to make money on it. That is the hard part.

Yes, if it your digital 3D business cards are novel and non-obvious then you should be able to get a patent on it.

If you have not disclosed your invention publicly before you apply for a patent, then you should be able to get a patent anywhere in the world. If you have disclosed it but... View More

A patent is a business tool. Just like a rice milling machine, or a tractor trailer truck, or a deep ocean trawler, or a customer list. It is just a tool.

What I ask people who are interested in getting a patent is whether they have a plan on how to monetize the patent that I could get... View More

Sorry, but you can't. Licensing terms, such as financials, are typically highly confidential.

The best that you can do is to find out whether the patent has been assigned to someone. Such assignments are typically recorded at the Patent Office.

There is no recourse. Sorry, but this is ancient history, and any rights that you might have had have long lapsed.
