Is it copyright infringement to remanufacture a discontinued lamp? « on: October 21, 2020, 04:52:38 AM » Author: WorldwideHIDCollectorUSA
Is it considered copyright infringement if someone was to try to put a discontinued light bulb back on the market such as SOX?

Not copyright, it sin't any art. But some patents covering some of the design aspects may still be "alive", so you would have to redesign them to go around.

It’s near on impossible to be able to reproduce SOX again, take a read of the ‘And so it ends’ thread and you will see what I mean!

What about manufacturing a new low pressure sodium lamp with a different design?

It’s not so much a new design, it’s how difficult the lamps were to make to start with, I think even the Chinese have given up on manufacturing them now?

In my opinion, I do believe that LPS lamps are considered a very environmentally friendly light source since their disposal process is very clean and that these lamps are extremely energy efficient.

Quote from: WorldwideHIDCollectorUSA on October 21, 2020, 04:08:14 PM ...that these lamps are extremely energy efficient. This is a myth now, it is by far not true anymore. They may seem to be extremely efficient (only the higher wattages, 90W and above) in the reference integrating sphere, but for real applications their enormous physical size makes it impossible to maintain any reasonable efficiency in the beam control optics. So most of the light only causes overillumination on many places and light pollution. So when you measure how much power you need to illuminate given area to a given level, LPS become far behind other technologies in most applications.

Quote from: Binarix128 on October 22, 2020, 08:14:24 AM Would it be a patent infringement if someone manufactures a fluorescent tube or a mercury vapor lamp with an Edison screw? Having just an Edison screw alone for sure not, that patent expired more than 100 years ago (patented by Edison along with the other lightbulb patents, it can be maintained max 30 years). But some design details of some specific screw detail (some heat or rust proofing, production method,...) could be still alive (if patented very recently, so the 30 year limit have not passed yet).

Quote from: Ash on October 23, 2020, 05:01:37 AM However, the screw base is also used on LED lamps so you can skip manufacturing it altogether and just buy it from any of the existing manufacturers But that may not be enough to protect you against patent claims. Some patents could be written so to cover some design detail when used only with e.g. glass bulb, so do not apply when the lamp body is e.g. plastic. But there I would expect the opposite to be more likely: Design details related to plastic parts around the lamps would have more likely still their patents valid. But with things like these sockets, where the base technology is old so active patents are unlikely, it is better to not actively look for any patents and take "an assumption it is general knowledge and there are no active patents". If there happen to be some, you may have to pay royalties for it, but they wont be that huge. On the other hand if you would be proven you knew about a patent (and a log in your ISP or in your browser history about you downloading some from e.g. Google Patents or so), the payment could get extremely high, because it now becomes a "willful infringement". And that is a serious legal business then.

Quote from: Binarix128 on October 23, 2020, 11:39:11 PM Seems like most basic lamps parts have not patents valid, because lamps with Edison screws, fluorescent tubes parts and its technology are being manufactured everywhere in China Generally the time you may maintain active patent is limited, in most jurisdictions it is somewhere around 30 years. Most of the basic stuff are way older inventions, so the related patend have already long expired. The only possible live patents could be some small "improvements", like (an example I just made up) using some specific new corrosion protection coating, which by itself could be known for ages in general metallurgy, but using it on a lamp may be the "novel" thing patented here.
