@jermaustin1 is right. Nuisance lawsuits rarely go to trial because the cost to litigate is far higher than the settlement demand. Patent assertion entities are usually looking for a quick payout and these cases typically do not last long. Many patent litigators will give you a free one-hour consultation. It does not hurt to ask. (Source: I am a patent litigator, and my firm does free one-hour consultations. I've even done longer ones for free. When you talk to the lawyer, just say that other firms are waiving the cost to discuss your initial options. That is not unusual at all.)
In an effort to add some clarity to the chaotic jurisprudence on Section 101 (patent eligibility), the USPTO recently introduced guidelines that make it easier to obtain software patents. These guidelines bind the examiners but not district courts. Given the USPTO's patentability court's (the PTAB) limited jurisdiction to hear and decide 101 challenges, I think the USPTO is going to keep churning out questionable software patents like Lockwood's. Because patents like Lockwood's rarely get litigated in district court, the problem of these shakedowns is not going to end until either (1) the PTAB gets some jurisdiction to decide 101 cases (a lower cost venture than district court) or (2) Congress steps in and clarifies the law. I do think that software implemented patents have a place, but the current state of affairs ain't it.
