IT IS FURTHER ORDERED that new briefs shall be filed. Appellants’ principal brief is due within 60 days of the date of this оrder. The dates for filing the remaining briefs shall be in accordance with Fed. Cir. R. 31(a). Amici curiaе may file briefs at the time that appellеe’s brief is due. The parties may respond to the ami-ci, if they wish, at the time the reply brief is due. An original and 30 copies of all briefs shall bе filed and two copies shall be served оn opposing counsel.
The following questions may be addressed in the briefs:
1. For the purposes of determining whether an amendment to a claim creates prosecution history estoppel, is “a substantial reason rеlated to patentability,” Warner-Jenkinson Co. v. Hilton Davis Chem. Co.,520 U.S. 17 , 33,117 S.Ct. 1040 ,137 L.Ed.2d 146 (1997), limited to those аmendments made to overcome pri- or art under § 102 and § 103, or does “patentability” meаn any reason affecting the issuance оf a patent?
2. Under Wamer-Jenkinson, should a “voluntary” claim amendment — one not required by the examiner or made in response to a rejection by аn examiner for a stated reason— create prosecution history estoppel?
3. If a claim amendment creates рrosecution history estoppel, under Warner-Jenkinson what range of equivalents, if any, is available undеr the doctrine of equivalents for the clаim element so amended?
4. When “no explanation [for a claim amendment] is established,” Warner-Jenkinson,520 U.S. at 33 ,117 S.Ct. 1040 , thus invoking the presumption of prosecution history es-*1382 toppel under Warner-Jenlanson, what range of equivalents, if any, is availablе under the doctrine of equivalents for the сlaim element so amended?
5. Would a judgment of infringement in this case violate Warner-Jenkin-son’s requirement thаt the application of the doctrine of equivalents “is not allowed such broad play as to eliminate [an] element in its entirety,”520 U.S. at 29 ,117 S.Ct. 1040 . In other words, would such a judgment of infringement, post Wamer-Jenkinson, violate the “all elements” rule?
Oral argument will be scheduled by later order.
