Making someone else's product
Making someone else's product
(OP)
For the past 10 years I have been maintaining and repairing traction motor resistors, for light rail cars, mostly by cannibalisation.
The maker a European company does not offer this particular part anymore. I am now getting to the stage where repairable parts are getting scarce.
My customer is now asking me, if I can fabricate these parts from scratch. Since this is Somebody Else's product, I do not feel comfortable just making them without some kind of written permission.
My customer is telling me, that the reason the manufacturer, will not, sell these parts to them, is that they are trying to sell them newer units ( Complete rail cars.) and that they are not likely to give me permission to fabricate an obsolete part.
What are the guidelines here? Make them until I get a cease and desist order, or not even try?
I see this kind of thing done with aftermarket suppliers in the automobile industry with older cars. Do they get permission?

RE: Making someone else's product
If the contract department of your customer was on top of things, they might already have the right to manufacturer parts that the original suppliers are no longer interested in providing. It's common to have appropriate provisions in current contracts for new rolling stock. Less common for stuff purchased 20ish or more years ago. If your customer does not already have appropriate rights, they are likely in better position to obtain them from the OEM than you are.
Otherwise, become a better vulture. There is DC traction equipment being thrown out en-mass by some transit authorities.

You may be pointing me in the right direction.
Quote:"If the contract department of your customer was on top of things, they might already have the right to manufacturer parts that the original suppliers are no longer interested in providing."
I am of course dealing with the maintenance and purchasing division of a bureaucratic organisation, not the contract division. You are right, these cars are 30 years old.
I now have to go up a level or two and ask the questions
As for becoming a better vulture the only other city I know of using this model of train car was in Canada not the USA.
What about the original question, manufacturing without permission?

RE: Making someone else's product
Another possibility is whether replacement parts are regulated by the government. I'm thinking this is highly regulated for the airline industry, maybe not so on the rail industry.
You might check if your liability insurance includes manufacturing.
If the manufacturer is currently trying to sell you new gear, then your purchasing people should be in a position to exert some major influence on your behalf to get these parts.

RE: Making someone else's product
These parts are buried in a box on the underside of the train car and the only person who ever sees them is the maintenance man.
So I do not think a trade mark issue would come up.

Reasons for seeking permission anyway include getting:
- a license for use of any patents that may apply.
- blueprints and specifications.
- nonobvious manufacturing processes.
As Mint hinted, getting up to speed could be an adventure.
Perhaps you can get a mfgr. of electric heaters to make a limited custom run on your behalf.

Thanks Mike,
The blueprints and specs are the main thing, I have these of course to effect the repairs
They also have the usual boilerplate about not using them without the manufacturers permission.
This is where I am getting hung up, fixing a makers product is one thing, using his drawings and specs to make his stuff on your own is another.
As for getting a heater manufacturer to make a limited run, he had better be someone making tape heaters for drop quench ovens or something like that.
The smallest and lightest resistor is fabricated from 3/4" wide by .020" chrome vanadium steel and the biggest are 7/8" by .070" Monel 67. They average between half to 2 ohms at about 3 to 5 kw. At between 600 to 800 volts working.

How do most owners get parts for old cars?
Not only from the manufacturers.
OK, so if you have an old MG there is (was?) a guy in Staines with a warehouse full of old MG TAs that are his Parts stock i.e. for canabalisation. Most every part for any old car has to be reproduced, reverse engineered, canabalised or adapted from some other part.
But even with modern cars the question of spare parts is seemingly quite open.
Mostly the concern about spare parts is if using generic parts voids the manufacturers warranty.
Once out of warranty, your choices are the manufacturer's spares or some equivalent part at half the price. Now all you have to worry about is quality.
Most auto-accessory stores will sell you parts that are made but anyone but the original manufacturer or by the original part manufacturer under another, cheaper, brand name.
So I would guess that the situation re your part is similar. The only exception would be for a component covered by a patent.

Not true. Patent infringement can be enforced against ANYONE in the chain, from manufacturer to consumer. McDonnell Douglas was sued for patent infringement by the Lemuelson Foundation for BUYING and USING commercially available bar codes and readers.

Do you have complete manufacturing drawings for these things?
It is easy to examine a part and scale dimensions off it. Working out the tolerances is more difficult. Working out the materials, heat treats and finishes is a challenge.

I have complete manufacuring drawings, tolerances, material specifications, and assembly instructions.

RE: Making someone else's product
In that case, the only problem I can see is any notes on the drawing stating that the information therein is property of the manufacturer, and may not be used without permission.
You can always threaten to identify them on Eng-tips!

That might depend on location (grin).

RE: Making someone else's product
That language is there and is the main reason I asked this question in the first place.
Right now I am waiting to see what comes back from my customers legal department.

RE: Making someone else's product
You sometimes see signs in car-parks etc. saying that "you leave your car at your risk and the management accepts no liability etc."
Nice try.
They cannot avoid all legal liability simply by saying so.
Similarly, some statements made may also not always be enforceable. Let us know what your legal guys say.... but please don't pass us the $/min legal charges.

Doing so using the OEM's own documentation where it contains disclaimer on not using or copying without notification or authorization is prosecutable, under which statute(s) varies by jurisdiction. Often it is copyright law that applies.
In the case discussed, I believe very simply a licence is needed from the OEM. Companies are not benevolent charities, however due to passage of time and/or 'abandonment' they might give authorization gratis, however expect to sign legal indemnification contract.
RE: Making someone else's product
Thank you for that opinion.
Right now I have the customers legal department checking the original contract, to see if it contains language, giving them the right to manufacture or cause to be manufactured, parts the original supplier is unwilling or unable to provide.

RE: Making someone else's product
Basically make a new part but use a couple of components or something from an old one?
KENAT, probably the least qualified checker you'll ever meet...
RE: Making someone else's product
Many times you can modify the shape a bit so it fits and functions the same but visually there is a difference between the two.

RE: Making someone else's product
Actually if there was a patent (and its expired) then you should be able to get the drawings at the patent office.

In the OP's case, I think that the only way to do what he wants cleanly and without risk of being liable is to receive the OEM permission.

Without these protections, we'd all be free to reverse engineer and copy their product. Our US laws provide no protection beyond patents, trademarks, and copyrights.
