The next episode of "The Big Bang Theory" season 9 will see the boys attempt to earn exclusive rights to a concept their group hatched. Titled "The Application Deterioration," the episode will see Sheldon  preparing a contract that will benefit them all.

As of this writing, there remains no information as to what idea the guys have come up with but it looks like patenting it won't be a walk in the park for them. The contract Sheldon will be assembling will see the share distributed in three parts.

The next episode of "The Big Bang Theory" season 9 will also see Raj caught in a love triangle as he always did in the recent episodes. The synopsis for the installment teases that he will "hear from" the girls.

For those who don't know, Raj split with Emily in "The Meemaw Materialization" in order to be with Claire, who turned out to have a boyfriend already. Claire also sort of led him on, making him think that she was into him when she wasn't.

It looks like "The Big Bang Theory" season 9 episode 18 won't resolve this complicated love triangle as Raj himself won't be able to decide. According to executive producer Steve Molaro, however, Emily may not be the right girl for him but it's not like he would mind. Raj seems to be more worried about not ending up with a woman at all.

"I think he knows in his heart that this might not be the right person for him, but, for a sensitive and insecure guy like him, the thought of choosing to break up with someone and be alone is difficult. That's something he will be wrestling with further in season 9," Molaro told TV Line.

"The Big Bang Theory" season 9 episode 18 will also see the girls discussing Bernadette's morning sickness. For those who are not in the know, the last two episodes revealed that Howard and she are welcoming their first child soon.

"The Big Bang Theory" season 9 episode 18 "The Application Deterioration" airs March 10 at 8 p.m. ET on CBS.
