`
`
`
`·1· · · ·Q· · Are you aware of occasions where a friction
`
`·2· ·fit is used to seal a chamber?
`
`·3· · · ·A· · I believe a friction fit can be used to seal a
`
`·4· ·chamber.
`
`·5· · · ·Q· · So a test tube with a snap-on cap would be a
`
`·6· ·friction fit that sealed the test tube?
`
`·7· · · · · · MR. KRAMER:· Objection to form.
`
`·8· · · · · · THE WITNESS:· Yeah.· I wouldn't really equate
`
`·9· ·a snap fit with a friction fit.
`
`10· · · · · · A test tube with a stopper inserted would be
`
`11· ·an example.
`
`12· ·BY MR. SACKSTEDER:
`
`13· · · ·Q· · So you draw a distinction between a snap-on
`
`14· ·cap and a friction fit?
`
`15· · · ·A· · Correct.
`
`16· · · ·Q· · Can you elaborate on that explain what the
`
`17· ·difference is?
`
`18· · · ·A· · Sure.· A snap fit typically involves
`
`19· ·displacing material and using the elastic properties of
`
`20· ·the material to come back to it, so that to remove
`
`21· ·something, you have to do mechanical work to displace
`
`22· ·it, to displace something, and overcome an
`
`23· ·interference.
`
`24· · · ·Q· · So and the example you gave was a stopper for
`
`25· ·a test tube?
`
`2
`
`
`
`·1· · · ·A· · Correct, as friction.
`
`·2· · · ·Q· · Okay.· In paragraph 18 in your discussion of
`
`·3· ·person of ordinary skill in the art, you say that a
`
`·4· ·person of ordinary skill in the art would have to have
`
`·5· ·some experience with medical experience, medical
`
`·6· ·devices.
`
`·7· · · · · · Do you see that?
`
`·8· · · ·A· · Yes, I do.
`
`·9· · · ·Q· · How much experience?
`
`10· · · ·A· · I think enough to understand the context of
`
`11· ·what's going on.
`
`12· · · ·Q· · And how much is that?
`
`13· · · ·A· · It all depends.· It could be very intense
`
`14· ·over, you know, a few days, or it could be less intense
`
`15· ·over a longer period of time.
`
`16· · · ·Q· · So it could be a long -- a fairly wide range?
`
`17· · · ·A· · Sure, it could be.· But it doesn't need to be.
`
`18· · · ·Q· · The spikes that are disclosed in the '424
`
`19· ·patent, they are not cylindrical.
`
`20· · · · · · Correct?
`
`21· · · · · · MR. KRAMER:· Objection to form.
`
`22· · · · · · THE WITNESS:· The ones in the embodiments are
`
`23· ·not, no.
`
`24· ·BY MR. SACKSTEDER:
`
`25· · · ·Q· · So to the extent that a trocar is cylindrical,
