Just a thought, not an answer: If it had used "Microsoft's Word", Microsoft could not possibly have had a copyright on the word "Word". However, since it uses "Microsoft Word", the whole syntagm can be copyrighted. All English-speakers can still use the word "word" without fattening Bill Gates' wallet. (Note the apostrophe after the "s" in Gates!)

In North America, the company formerly called Radio Shack is now called "The Source, by Circuit City". It could have been called "Circuit City's The Source" but then, that would have turned into a slogan, wouldn't it?

One solution to your client's problem in this case would be to drop the plural form "Technologies" from its name and go with "Jupiter Technology Solutions". The singular blends right in.

MicroSoft Word is a product trademarked proper noun name construction, because the Word software might even be a product that was licensed from someone else and marketed with this name.
MicroSoft's solution to the need for text processing is MicroSoft Word.
The same applies to Fiat's range of cars - the Fiat Bravo and your Fiat Panda.
MacClaren's commercial car is the MacClaren F1.

Thus, Jupiter Technologies' Solutions is the grammatically correct title of the profile in which they can enthuse about Jupiter Techologies TV, for example, and any other trademarked product names they want to incorporate their company name into.

If, however, Solutions is a product in its own right that they have registered as Jupiter Technologies Solutions, then they would be right.

When all is said and done, the client will make the final decision anyway! That does not make it grammatically correct - it is just what they are prepared to pay for.

It's fine without the apostrophe. In this case, "Jupiter Technologies" acts like an adjective, not a possessive. With the apostrophe is fine, too, just as "Microsoft's Word" works. It probably sounds odd simply because it is such an established term without the apostrophe.

I'd say, if your client prefers it without, let them have it that way.

Sorry, make that Solutions (capitalized) if it is a heading.
