Is there some legal reason to scatter announcements with that many ® symbols, or do they just do it for style reasons / because they think it makes the announcement look more impressive?
When you are making the absurd case you’ve trademarked “speed test”, yes, you have to take pains to mark it.
i'm guessing that part of accenture's consulting business is helping people navigate the trademark registration process. so they've got to hype up the ®.
Legal. Gotta protect your trademarks.
Using the symbol allows them greater protection under the Lanham act, because it counts as “notice” that the mark is registered.
Without it, it limits your ability to recover damages from infringement.
