Joint defense groups are great for saving money on these things.

Having been in several, I've noticed a few areas to navigate carefully. It's worth making sure that everyone is comfortable with the strategy. Assuming the group tries to kill the patent, the acts of the group may limit what the individuals can do later in their defense, e.g., a weak group effort could prevent an individual from later asserting certain invalidity grounds. See e.g., part e of https://www.law.cornell.edu/uscode/text/35/315. On the other hand, often some group members don't want to pay their share for a gold-plated attack, e.g., those on a tighter budget or with less exposure.

I wouldn't let that deter me, though, from seeking a joint defense group. This seems like a great idea.

That's sage advice right there. Would love to chat more, if you have the time. You know where to find us.
