Hmmmm. Not preferred. Just abandoned, surpressed, or concealed "alternative" embodiments of "the invention". Absent details you obviously can't provide here, sounds like "walking brain fharts" to me. Didn't you capture "the invention" alredy? OK stuff happens. Send draft claims then later, after client OK, snd draft app to client, they come back with "well, couldn't we do this or that too?" Totally blowing well-concieved claim strategy out of water. We've all been there and done that. As it is was said on the improptu drag strips in 60s: "run what ya brung" (i.e. man up). Tough to hit a moving target. IMO file claims to "the invention", then as many apps with Jepson claims as client will pay for. I don't file a lot of Jepsons. But I don't diss them either (promises by another here to screw me in court notwithstanding - I occasionally file Jepson claims. Bring it on dude!). OK seriously, I repeat; didn't you captutre "the invention" in the original app? Just file a bunch of CIPs - after the retainer checks clear.
