What is the status of this patent? Recently I received a warning from someone who seller that says I am infringing on their utility patent. While looking up their patent, I am seeing different information about the status. 1) Source 1: Google Patents Google Patents says the latest status is: 2019-08-12 Application status is Active. 2) Source 2: USPTO https://portal.uspto.gov/pair/PublicPair It says Status: Application Involved in Court Proceedings. Also, when I click on the "Image File Wrapper" tab, the latest update on 04-08-2019 shows that the patent was dismissed by the court So is the patent rejected or accepted?
That is not at all what USPTO is telling you. Courts do not simply "dismiss" patents - that isn't a terminology you'd ever see used for a patent that was found to be invalid. Timeline of events: United Industries Corporation brought a suit against the owner of the patent, claiming unpatentability. That case went to trial, and the court found the claim to be invalid and that UIC failed to show unpatentability. UIC appealed that decision to the Court of Appeals. The Court of Appeals dismissed the case because both parties agreed to its dismissal (it's possible they reached some external agreement we don't know about). As far as I can tell, at this moment, the patent is active.
In US law, a trademark application only requires that you are now selling, or intend to sell in the reasonably near future, a product (or service) using the specified name. You don't have to provide an example, or a design, and it does not have to be patented. The applicant might be planning to license someone else's patent, or to market off-the-shelf tech not protected by patent. The applicant might be planning to market tech still under development and not yet ready to be submitted for a patent. I do not know Chinese trademark law, but I suspect it is similar in this regard. I have not heard of any country that requires a patent, a design, or an example of a working product along with a trademark registration. However, there is, in many countries, a requirement that actual sales occur within a limited period after the trademark is granted, and if this does not happen, the trademark registration may be canceled. The time allowed varies.
For the first question - No, patents are territorial. A US patent is not &quot;working&quot; anywhere else. Of course one can apply in multiple countries if the proper time frames and procedures are followed. There is a mechanism (PCT Treaty) that allows a straightforward way to apply in over a 140 countries simultaneously. Although it is frequently used, it is expensive to continue to prosecute the application in each place and even in high-value inventions only a handful of places are eventually chosen to actually pursue patents. Each country's/region's laws and processes are different and success in patenting can vary. Normally two countries would not have the same thing patented by different inventors. The patenting or publication of the first one would make it prior art to the second filed one. This should be found by the second examiner and stop a duplicate patent by a second inventor. However there can be subtle differences between similar inventions and mistakes do happen. In the case of true simultaneous invention this can happen. To get a patent, the invention must be novel - that means no one has published or patented it anywhere in the world at any time in any language. Before the AIA law in the U.S. the law said &quot;or known in this country&quot;. It could have made a loophole where something was known publicly elsewhere but did not constitute prior art in the U.S. That is now changed to be world-wide. Even if the examiner does a world wide search they might miss something and a patent might get issued even though the invention was not novel and a patent elsewhere is granted. To invalidate it the original patent owner would need to look into available procedures in country A. It might be court or it might be administrative. In most places an annual “renewal” fee must be paid to keep a patent in-force. In the U.S. a “maintenance” fee must be paid at the 3.5 year, 7.5 year and 7.5 year points in order to stay in-force. A patent who’s renewal or maintenance fee hasn’t been paid is expired for fee reasons. That can imply that it can be revived by the patent owner by paying the fees and usually a penalty. There may be a time limit or a small set of allowable circumstances to revive. A patent labeled expired for fee reasons might now be past its normal lifespan and therefore not revivable. In general patents are given to inventors and those an inventor assigns their rights to. Someone else can’t come along and revive a patent they had nothing to do with originally. There is no “re-patenting”.
Before the AIA in 2012 both companies could apply for a patent and if one of the applicants thought they were both trying to patent the same thing they could initiate an interference proceeding. In that proceeding before the board, they each present their evidence as to date of conception and diligent effort from that point to the date of the first filing. The board decided which application went forward. Now the U.S. is with the rest of the world in first-to-file. It doesn’t matter who conceived first unless one actually stole the idea from the other. There is a new derivation procedure to try to prove that. I don’t think it has ever yet happened. One of the &quot;simultaneous&quot; inventors could publish the invention, putting into the public domain. If published before the other's filing date, it would theoretically prevent the other from getting a patent. In any case a patent owner can stop the other from making their product or charge a royalty. There is a narrow case under the AIA where one company has been using a process that another later patents and can retain a limited right to keep using that process but can’t move or expand operations. This is called Prior User Rights.
Court filings are, in general, matters of public record. This does not automatically put them into the public domain. This will mean that, absent a special order of the court, anyone will be able to read this filing as pert of the court records. Many courts now make all or parts of their records available on the web. But the copyright holders will possibly retain their rights to authorize the making of further copies, and surely retain the right to authorize the making of derivative works, and their other rights that are part of the copyright bundle, such as the rights of public performance. These rights would not be retained if the work had been placed in the public domain.
If it's patented then it doesn't matter that you independently came up with it. Most software is not patented, though. Most developers do not even think about patents when writing code. In theory you could spend your time keeping up to date on software patents so that you avoid infringing. But this probably only makes sense for specialists who would want to read the latest patents in their field anyway. All software is protected by literary copyright, though. In this case they will try to prove that you did not independently created it, and did copy it. Whelan v. Jaslow in 1986 ruled that structure, sequence and organization of a computer program were protected by copyright. So you could be liable even if you did not just copy and paste sections of code. But even if you're worried the court would get things wrong and think you copied a program when you never even saw it in the first place, there is really nothing you can do about it.
This overstates the case. A company must pursue infringements, arguably even when it isn't economically sensible in isolation to do so, to prevent its trademark from being diluted. But, that isn't the case &quot;when it's blatantly obvious that there is no infringement.&quot; There is no benefit from pursuing cases that aren't even colorable infringements. The notion is similar to adverse possession. If you let someone openly use your real property without your permission, eventually, the squatter becomes its legal owner. Also, as in the case of adverse possession, an alternative to suing someone for infringing is to make their permission non-infringing by writing them a letter expressly authorizing them to use your mark. Permissive, licensed use does not dilute a trademark.
Being or not being open source makes fairly little difference in trademark law. If a commercial firm (Yoyodyne, say) had used the name &quot;Portable Network Graphics&quot; and the abbreviation &quot;PNG&quot; in trade, and taken such further steps as would be needed to protect it in the relevant countries, that firm would have a protectable trademark. Note that in some countries, a trademark must be registered to have any protection at all (much of the EU follows this rule). In others, use in commerce can offer some protection even without registration (the US follows this rule). Had this happened (in an alternate reality) Yoyodyne could have sent a cease and desist letter when open source developers started using the mark. If the devs did not cease, Yoyodyne might have obtained an injunction, or damages for trademark infringement, or both. They could also have issued a takedown notie to the site hosting the project. But had Yoyodyne failed to defend the mark effectively and allowed it to become generic, Yoyodyne might have lost all rights to it. Also, had Yoyodyne ceased to use it in trade for a significant period, they might have lost rights. This is a place where the different laws in different countries might lead to different results. Note that &quot;Portable Network Graphics&quot; is rather descriptive, and not particularly distinctive. Descriptive marks, like &quot;Tasty Pizza&quot; generally get weaker protection, while more distinctive marks, such as &quot;LuAnn's Tastee Pizza&quot; are more strongly protected, in general. Again this depends on the country, and the specific facts. In general the first to use, or to register a mark, gets the rights. When one entity is the first to use, but a different one is first to register, things can get confusing, and results will be different in different countries. Note that a Cease and Desist letter is not a legal requirement. It is a threat of possible future legal action, and often an offer to avoid such action if the recipient does as the sender requests. The recipient can comply with the letter, wait for court action, or try to make some sort of compromise deal. Open source projects, as other answers suggest, often choose to comply.
