Why can multiple companies make wind turbines? Why don&#39;t they run into patent violations? I am curious to know that how it can be that so many companies can build wind turbines. Did these companies buy the patent from the inventor of wind turbine? Or is this technology not patentable? Or did no one bother to patent this technology? Suppose, hypothetically, that I am the inventor of the wind turbine. How can I protect my idea to prevent it from being duplicated?
Of course windmills/turbines in general are not new and one would not need a license or permission to make and sell a &quot;generic&quot; wind turbine. But there are new types of wind mills invented and patented all the time. Examples are US7821148B2 Wind turbine and US8441138B2 Wind turbine. Patents are complicated and an inventor of a new type of windmill might need to license other people's patents that are broader in order to be able to make their new invention. Most windmill inventions are to improvements in components. It is a very rich field. As a small example, I helped a client get a patent on a device that is attached inside a windmill tower that prevents maintenance workers hitting their heads on part of the structure as they climb up. The second part of your question was how you can protect an invention you might make. Technology can be protected by patents both design and utility and some things might be able to be kept trade secrets (but not both for the same thing).
If the patent lawyer &quot;hears about&quot; such failed patents from clients, and then uses the client's work and modifies them into successful patent filings, that would seem to be a clear conflict of interest, just as a business lawyer cannot use info learned from a client to make his own business deals, unless the client grants an OK. But if the patent lawyer just hears through shoptalk, or through communication by, perhaps, patent examiners that the lawyer works with, I don't see any conflict of interest, although as the comment by Eugene Styer suggests, there is likely to be enough prior art to make the patent invalid.
The software being free and open source has no impact on whether it infringes any patents or violates any copyrights. Copyrights attach to fixed representations of creative work in a tangible medium (e.g., the actual code and graphical elements of the software in question). As long as you aren't copying the copyrighted work of someone else, you should be in the clear. So, if you write your own code from scratch, or rely on code that you're allowed to use (e.g., "free" software with a permissive license that allows it to be used freely), you should be fine. On the other hand, if you copy a chunk of code that you aren't allowed to use, and then change the variable names so that it's superficially different, you're likely violating someone's copyright. Patents are a much more difficult question. To determine whether you would infringe any patents, you would have to read the independent claims of every patent that might be related. If you perform all the steps of any one of those claims, then you are infringing that claim (and therefore, the patent in which it is found). Unfortunately, this is much easier said than done. First, it may be difficult to search for all the potentially relevant patents, and once you've found them, there may be far too many to read. Second, claims are written in a type of language that is specific to patents, and someone without experience in patent law may not understand them correctly. Finally, the terms in the claims may not take on their plain English meaning, but rather may have been defined by the language in the rest of that patent, so it's possible that you might incorrectly think you were in the clear based on a misunderstanding arising from that. All that said, it may be best to go ahead with implementing an idea and then waiting to see what happens. Chances are that the implementation will arguably infringe some patent in some way, no matter what's done. But chances are also high that there will never be any worrisome enforcement action taken against it by a patent owner, simply due to the difficulty and expense associated with enforcing patent rights.
No Because it’s patented in country A, it is not novel anywhere in the world. That is, the patent in country A is “prior art” that would disqualify it from being patented anywhere else. The original patent holder can patent it elsewhere because patent law has an exception for that.
Provided you are in one of the 170+ countries signatory to the Berne Convention (the current 10 non-signatories are, exhaustively: Eritrea, Marshall Islands, Nauru, Palau, San Marino, Iran, Iraq, Ethiopia, Somalia, and South Sudan), then copyright comes into existence at the moment a work is fixed in a tangible medium, not when it is published. The initial copyright owner is the author of the work. In cases of employment, the "author" might be the natural person who authored the work, or the corporate person who employed the natural author. To clarify your thinking about registration: copyright registration is a public record of authorship (or copyright ownership). Registration does not create a copyright, but is merely a recording of the copyright that was automatically created at the moment of original authorship. Depending on circumstances and jurisdiction, Alan might have a legitimate claim to copyright on his own work. However, he will be quite hard-pressed to find a convincing theory of law that allows him to publish the unpublished copyrighted work of other people without their permission. This leaves him either to admit defeat -- he cannot possibly own the copyright of his coworkers' code, so he cannot have legally reproduced it -- or else make the baldfaced lie that the code has no other authors other than Alan himself. For your company to disprove such a claim, you may employ sworn testimony of your coworkers, you may employ code analysis to show differing coding styles (suggestive of multiple authors), or you may show code backups or version control history showing the progressive authorship of the work over time by many people. (Sure, a Git history is possible to fake, but a realistic history with feature branches, "whoops, undid the typo in the last commit" messages, etc. would lend significant weight to your company being the original authors.)
Summary: More information needed, but I have listed out some legal claims available to homeowners when they have similar concerns. There are several issues here which need elaboration before deciding if you can take legal action. The first is: "the destroyed some vegetation on my street." If the by "my street" you mean that the street is part of your property, you may sue the builders for trespass and/or damage to property. If the street isn't your property, but the vegetation is your property, you may sue them for destruction of your property. What you are probably looking for, however, is a prohibitive injunction. This is a court order forcing the builders to avoid doing something, e.g. An order forcing them to avoid using roads adjacent to your property. To obtain such an injunction you will have to prove that what they are doing is violating your rights, is somehow harmful to you or your property, or inevitably will do either of those things. One way to demonstrate this is if you can show that you have a claim under nuisance, or damage to property, or trespass. On the description you have given us, there isn't enough to say your rights are being violated, or that your property has come to harm or will come to harm because of their actions. You should also be aware of claims under nuisance. Nuisance is when someone is doing something that prevents you from "peaceful enjoyment of your land". It appears from your question that the actions of these builders have, in your mind, done this. However there are several aspects that have to be satisfied for this to amount to private nuisance: What the builder are doing must be a "continuing state of affairs." They may have annoyed you by trampling over vegetation, but if this is a "one-off" event, it is unlikely to amount to nuisance. A reasonable person must find the conduct to interfere with the enjoyment of their land. That is to say: it isn't enough that their conduct is making you unable to enjoy your land peacefully, you have to show that any reasonable person in the same situation would find this conduct unacceptable. Finally, the context of your neighbourhood matters: if the behaviour is something expected in a residential area, then it will not amount to a nuisance. For example, heavy drilling in an industrial location will not amount to a nuisance, while the same may do so in a normally quiet neighbourhood.
could this mean my employer owns the idea and anything I develop --since I would use the same technology for my idea that I do at work? No, unless by &quot;technology&quot; you mean the employer's materials or resources (see condition 3 of the clause). Your remark that &quot;this is completely and utterly unrelated to [employer's] business model&quot; survives items 1 and 2. Likewise, working on your idea outside hours survives the corresponding part of item 3. Would this also mean that any open-source software I develop outside of work automatically belongs to my employer? No, unless the software you develop is &quot;based on [your] knowledge [etc.] of (COMPANY)&quot;.
While it is not illegal to own, it may still be illegal to ride on public property. Private property owners can ban them even if they were legal and need to be consulted individually. I have been unable to find out if new laws spoken about have been passed in New York since the beginning of the year. Based on what I have found (as of the end of 2015), it would be best to consider that they are illegal to use on public areas just as any other unlicensed motor vehicle. As of November 2015 Some property owners have banned them for liability reasons, as it is easy to see how a rider could trip on a bump or unexpected curb. And although they have taken the Upper East Side and other parts of New York City by storm, the state classifies them as motorized vehicles that cannot be registered, so riding them in public can incur a steep fine. Earlier this week, the NYPD's 26th Precinct tweeted: "Be advised that the electric hoverboard is illegal as per NYC Admin. Code 19-176.2*." and December 2015 some lawmakers were talking about making them legal. Truth or Fiction Collected on: 12/28/2015 gives the following summary A spokesperson for the New York City Department of Transportation has explained that the law’s definition of “electronic personal assist mobility device” was broad enough to include hoverboards, and that they would be regulated as such. In NYC, because the population is above 1 million people, electronic personal assist device riders must be licensed, and the devices must be registered with the New York State Department of Motor Vehicles. Hoverboards are illegal, the spokesperson said, because the NYSDMV would refuse to register them for legal use: NYSDMV’s position is that these vehicles are likely “Electric personal assist mobility devices.” NYS Vehicle and Traffic Law 114-d defines “Electric personal assist mobility device” as “Every self-balancing, two non-tandem wheeled device designed to transport one person by means of an electric propulsion system with an average output of not more than seven hundred fifty watts (one horsepower), and the maximum speed of which on a paved level surface, when propelled solely by its electric propulsion system while ridden by an operator weighing one hundred seventy pounds, is less than twelve and one-half miles per hour.” NYS VTL 125 generally defines “motor vehicles” as “Every vehicle operated or driven upon a public highway which is propelled by any power other than muscular power.” However, VTL 125 specifically excludes some classes of vehicles from the definition of “motor vehicles.” Under VTL 126(a-1), “electrical personal assistive mobility devices operated outside a city with a population of one million or more” are not considered motor vehicles. However, in NYC, because the city population is greater than one million, NYSDMV considers “hoverboards” that meet the definition of “electric personal assist mobility devices” the same as motor vehicles. Based on that interpretation, it would be illegal to operate a hoverboard in NYC without a valid license to drive a motor vehicle. Beyond that, the motor vehicle would need to be registered by NYSDMV (which NYSDMV will not do), inspected, insured, and otherwise treated as, and subject to regulation like, any other motor vehicle. A person who operates a hoverboard in NYC (or any other NYS city with a population greater than a million) would be subject to arrest and prosecution for myriad NYS VTL violations, including, but not limited to, driving a motor vehicle without valid registration or insurance.
