Is it legal to copy property&#39;s listing from other&#39;s website as the question suggest. I've built a scrapper which scraps two websites to get property listing from there. As someone told me to scrape other website is illegal. but I think the listing ad of property is not a property of website. so I can scrape it. can someone tell me it is legal to get others property advertisment?
"...the listing ad of property is not a property of website." Why do you think that? Just because a website exists does not mean you can legally scrape it. Read the Terms of Service of the site; there is a good chance the TOS forbids scraping or copying of any part of the website in any manner, including scraping. If the property listings are from a third party service that provides real estate listings to websites, then those property listings are licensed to that website, and by scraping them you will likely be violating the TOSs of those two services. By illegally scraping the content of a website, you are opening yourself up to being involved in copyright infringement and/or being liable to be the subject of a civil lawsuit.
Yet I publicly wear shirts with copyrighted designs all the time. I'm unclear about this; do you mean T-shirts you have made yourself using copyrighted images or T-shirts you have bought? If the former then it is a prima facie breach and you could be sued by the copyright holder. You would probably not be as it would be impracticable. If the latter then there are 2 possibilities: The manufacturer/distributer/retailer chain all hold valid licences to put the image on a T-shirt and display it in the usual way so there is no breach involved. The manufacturer/distributer/retailer chain does not hold a valid licence in which case there is a breach and the copyright holder would target, say Wall-Mart rather than you. what about displaying ... works of art in my yard? Notwithstanding that it can be viewed from a public space, your yard is not public; therefore this is not public display.
You cannot use a trademark in a way that may cause confusion that your goods and services are associated with or endorsed by the trade marked goods and services. If you are clear that they are not then you shouldn't have any problems on that front. You also cannot defame the brand: that is make derogatory comments that are not true. On a practical note, when Pepsi (for example) sends you a cease &amp; desist notice, what are you going to do? They can go to the petty cash tin for $2 million to make your life a legal hell for 18-36 months: how much do you have to defend your rights?
In the abstract, two businesses that cooperate in violating a third party's copyright could both face liability. Applying that information to the facts you gave would amount to legal counsel. If you don't want to tell the client 'no,' you should speak to a lawyer about your potential liability. Beyond the legalities, do you really want your portfolio to advertise that you design sites by ripping other sites off?
The standard for fair use of trademarks is as follows: (1) the product or service in question is not readily identifiable without use of the trademark (2) only so much of the mark as is reasonably necessary to identify the product or service is used (3) use of the mark does not suggest sponsorship or endorsement by the trademark owner. I think you might run into a problem with (1). In other words the trademark owner would argue that you could have used fake trademarks to satisfy your product description needs, so you are using their trademark unnecessarily.
Is it legal in the US for a company that rents out car parking spaces, to bundle the renting of a parking space to buying insurance for the content of the parked car? Yes. Honestly, I'm a little surprised that I've never see this practice in real life. All things not prohibited are allowed, and there is nothing, per se illegal about bundling services and requiring them to be purchased as a package deal (there may be some licensing issues for insurance sales involved, but those would probably be easily overcome). Sometimes bundling gives rise to an anti-trust violation, but neither the parking lot operation business nor the car insurance business are so consolidated that this would fairly be viewed as some kind of anti-competitive practice.
It turns out that there is no difference between the ethical answer and the legal answer, in this case. The law recognizes the property right which a person has when they create a thing, such as a font, and that right is encoded in the law of copyright. The relevant US federal code is contained in Title 17, which you can read (essentially identical laws exist in virtually or perhaps actually all countries). The important thing to understand is that there is not a distinction between "privately" trespassing on a person's property and "publicly" trespassing on a person's property. The violation of the owner's property rights comes from taking the material without consent. There is a legally-recognized exception to the owner's rights, in the form of "fair use", which is widely misunderstood to mean "if it's not for profit, the property owner has no legal protection". Simply taking and using someone else's IP non-commercially is not "fair use".
You are absolutely allowed to discuss or describe or criticizes software (or books or other copyrighted or trademarked things) without any permission from the copyright holder or trademark holder. This includes teaching people how to use those things. You may not, however, copy protected software without permission. For example you could not include a CD with a copy of Windows 10 as part of a course you taught on using Windows 10, without permission from Microsoft. Also, you may not use a trademark in such a way as to imply that your course is approved or endorsed by the trade mark holder, or by the maker of the trademarked item. If reasonable people could think that your Windows course was approved by Microsoft, you are probably infringing their trademark. Use of screenshots is more of a grey area. Such use, for purposes of teaching or of commentary, is probably covered by fair use (in the US) or fair dealing (in any of several other countries). But that is always a case-by-case determination, and depends on the exact facts, such as how extensive the use is, and whether it in any way harms the market for the original. If in doubt consulting a lawyer experienced in IP issues is wise. But aside from the issues of screenshots, the makers or copyright or trademark holders of software have no right to grant or withhold permission to one who teaches about the softrware, nor to demand any fee from any such person.
