Bonus link, what you're experiencing is an example of cognitive bias because of priming. With the Samsung case fresh in your memory, you see Apple as launching a whole new wave of litigation, when their lawyers have been being lawyers all along: http://rationalwiki.org/wiki/Priming
"A simple example is the familiar "red car" phenomenon where a person who buys a red car suddenly starts seeing red cars everywhere. The familiarity of the red car primes them to spot other red cars faster."
This demonstrates that you are educated and have a special love for teaching, an adorable trait that, honestly, I very much appreciate. I would like for you to consider though that priming might not apply here unless Apple legal team has been doing this stuff more than once before Steve Jobs passed away, and I just didn't notice or remember a single article about it.
Not to mention that the case you pointed me to (and more on http://www.engadget.com/search/?q=apple+trademark) look way more legitimate, because there is some kind of a visual resemblance with the Apple logo, the grocery store on the other hand is totally different visually and I think it is extremely unlikely that a consumer may be confused by it.
I'm not sure I'm as altruistic in wanting to teach as opposed to the xkcd 'someone is wrong on the internet' thing, but I should point out the Woolworths trademark dispute that I linked to is a grocery store (but perhaps I'm not parsing the meaning of your comment?).
The thing about trademark disputes by Apple with grocery stores, and Microsoft recently with the European company with the 'Metro' trademark dispute is because the 'post-pc' era isn't fundamentally 'technology gadgets', it's new storefronts and marketplaces.
Amazon and their Kindles are about strengthening their digital storefront/marketplace.
Apple's iPad is arguably the most successful new model storefront/marketplace. It's like the high-end mall of virtual marketplaces.
This is a very real contested battleground. It's not about the apps, it's about the retail storefronts, both physical and virtual.
