How long do design patents last

Likewise, your patent-related licensing agreements will no longer be enforceable. Most agreements account for this by defining the term of the agreement as concluding upon expiration of the last licensed patent. If patent protection lasted indefinitely, it would put limits and excessive constraints on further innovation as the invention would never be able to be used by a third party to build upon them or advance other technology.

The length of protection for a patent gives the owner a significant amount of time to recoup their investment and establish dominance in the marketplace while keeping from slowing down innovation after their expiration. Consider the patent for the first telephone. If patents remained enforceable indefinitely, anyone who wanted to improve on the original design would have needed to obtain permission from the original patent holder.

This would have given one man a monopoly on the innovation of the telephone. For example, the telephone may never have developed into a cordless design and then into cell phones, and the smartphones that we know today may look nothing like what we know.

If that one man or company then built on the original patent, a massive and endless monopoly would develop, and no one else would be able to compete unless they built a completely different product. On a functional level, patents expire when the owner fails to pay the maintenance fees on a utility patent or the patent reaches the end of its term. This would be at the year mark for a utility patent or at 15 years for a design patent.

Utility patents require the owner to pay a maintenance fee at 3. It should be no surprise that some of the most successful companies in business today own software patents. Here are a few examples of software patents that are owned by companies you are likely familiar with. Businesses that do the majority of their work online spend just as much time developing their software as they do transacting with their customers.

This online homestay booking website has a patent on its software that automatically determines the booking availability of accommodation listings. Also, the benefit of applying for a design patent is that the amount of time it takes to prosecute and get a design patent is not deducted from the amount of time a design patent is good for.

This is so because the 15 years design patent term starts when the patent office grants the design patent and not when the design patent is filed. Design patents remain secret while they are pending at the USPTO, they are only published once the patent office grants the design patent application. Design patents protect the aesthetics and nonfunctional appearance of an invention. Said differently, an inventor can use a design patent to protect how his product looks.

That said, an inventor cannot use a design patent to protect how his invention works. While design patents are limited in what they protect, they are important to obtain in circumstances where the look of a product plays a major role in the purchasing decision of customers, i.

By obtaining a design patent on the appearance of your product, you will be able to prohibit others from making, using, and selling a product that has a similar design to your product for a limited period of time usually 15 years for design patents. Design patents do not protect the functional aspects of an invention. The line between what can and cannot be protected by a design patent is sometimes blurred when the appearance of an item is new and unique and offers utility at the same time.

Under these circumstances, you should consider filing for both a utility patent and a design patent. Protecting your invention with both types of patents adds value to your intellectual property. That said, the patent office also states that you should expect the first office action to be mailed out to you within Inventors often choose to obtain a design patent on their invention, in addition to a utility patent, because design patents are almost always less expensive to get than utility patents.

In total, you should expect to pay the following to obtain a design patent:. Unfortunately, design patents cannot be renewed once they expire.

Design patents are good for 15 years from the date the patent office grants them. At the end of the 15 year patent term, the patent expires and becomes part of the public domain, meaning anyone can use the design without the express consent of the patent holder.

Plant patents are issued for fruits, seeds, and plants. Other Barriers to Ongoing Patent Protection A patent may expire if its owner fails to pay required maintenance fees to the U. Stages of a Patent's Life Beyond the duration of the patent referenced above, inventors should be familiar with a patent's overall life stages.

The law actually recognizes five distinct "rights" periods in the life of an invention: Invention conceived but not yet documented. When an inventor conceives an invention, but hasn't yet made any written, signed, dated, and witnessed record of it, the inventor has no rights whatsoever.

Invention documented but patent application not yet filed. After making a proper, signed, dated, and witnessed documentation of an invention, the inventor has valuable rights against any inventor who later conceives the same invention and applies for a patent. The invention may also be treated as a "trade secret"—that is, kept confidential—which gives the inventor the legal right to sue and recover damages against anyone who immorally learns of the invention for example, through industrial spying.

Patent pending patent application filed but not yet issued. During the patent pending period, including the one-year period after a provisional patent application is filed, the inventor's rights are the same as in Period 2, above. With one exception, discussed below, a patent application does not give an inventor any extra rights—only the hope of a future monopoly that begins when a patent issues. However, most companies that manufacture a product that is the subject of a pending patent application will mark the product "patent pending" in order to warn potential copiers that if they copy the product, they may have to stop later and thus scrap all their molds and tooling if and when a patent issues.

Eighteen months after filing, and while the application is pending, the USPTO will publish the application unless the applicant files a Nonpublication Request at the time of filing and doesn't file for a patent outside the United States. If the application is published during the pendency period, an inventor can later obtain royalties from an infringer from the date of publication provided 1 the application later issues as a patent; and 2 the infringer had actual notice of the published application.

In-force patent patent issued but has not yet expired. After the patent issues, the patent owner can bring and maintain a lawsuit for patent infringement against anyone who makes, uses, or sells the invention without permission.

The patent's in-force period lasts from the date it issues until it expires. Also, after the patent issues, it becomes a public record or publication that blocks others from getting patents on the same or similar inventions—that is, it becomes "prior art" to anyone who files a subsequent patent application.

Patent expired. After the patent expires, the patent owner has no further rights, although infringement suits can still be brought for any infringement that occurred during the patent's in-force period, as long as the suit is filed within the time required by law. An expired patent remains a valid "prior-art reference" forever.
