Application 10/194,032
We REVERSE.
I. BACKGROUND
The invention relates to material useful as the active material for a
positive electrode of a non-aqueous electrolyte battery. The material
comprises pore free primary 1-300 nm particles of a compound containing
lithium and iron. The compound is, for instance, LixFeOy where 0 < x ≤ 1.5
and 1.8 < y < 2.2 (claim 26), LiFePO4, or LiFeCl4 (claim 35). Claim 18 is
illustrative of the subject matter on appeal:
18. A material useful in [sic] as a positive electrode active
material, said material comprising pore free primary particles of an
iron compound, wherein the primary particles are 1 to 300 nm, and
wherein the iron compound comprises lithium.
The Examiner relies on the following prior art references to show
unpatentability:
Goodenough US 5,910,382 Jun. 8, 1999
Kumar US 6,607,706 B1 Aug. 19, 2003
Yong S. Zhen, Kenneth E. Hrdina, and Robert J. Remick, A New Process
for Preparing Nanosize Ceramic Powders, 351 Materials Research Society
Symposium Proceedings 425 (1994).
The Examiner maintains two grounds of rejection:1 (1) claims 18-27,
30, 31, 34, 37, and 39-41 rejected under 35 U.S.C. § 102(b) as anticipated by
Zhen;2 and (2) claims 18, 35, 36, and 38 rejected under 35 U.S.C. § 103(a)
as being unpatentable over Goodenough in view of Kumar.
1 The Examiner has withdrawn the anticipation rejection over Miyaji.
2 The Examiner lists claims 28, 29, 32, and 33 as rejected, but these claims
have been cancelled. Therefore, we do not list them.
