Selling in the mid to lower $300 range, there is no doubt that it's price will get some attention. The real question, however, is if, upon inspection, if it's quality is equally in low as its price. If its quality is noticeably above its already low price, and if it shoots well, then Marlin should hav some success with it.
I don't think that it looks like a Savage, but it sure does have some similarities. I'm a corporate and business litigation attorney (not a patent attorney), but in my limited practice with patent cases, I would imagine that Savage could bring an infringement suit. Whether or not Savage would prevail is another story. However, from a strategy standpoint, I would imagine that Savage would first wait and see how well these new Marlins are selling. If they don't, then I would imagine that Savage wouldn't do anything. However, if these Marlins are starting to sell, and take some market share away from Savage, then I can see Savage filing suit for 2 related reasons: 1) Marlin would be taking market share from Savage, and 2) Savage would thus be able to prove "damages" (an all important element in lawsuits).
Note that I do not think that Savage would wait forever to establish their damages because then Marlin would have some money to pay their lawyers. As such, I would imagine that Savage would file suit at the initial stages when it sees (if at all) if sales of these Marlin rifles are starting to steadily climb.
Truthfully, and as many of you know, I'm more of a Tikka/Sako/Remington/Kimber fan. As such, I am more interested in this from a legal standpoint than anything else.
