DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
Formal matter:
The new filing receipt disagrees with the new Oath.
112 rejections:
Claims 2, 4 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
The ‘preferably’ sub-limitations in claims 2 and 4 are improper and unclear if they limit the claims.
Allowable subject matter:
Luo 20220126267 is noted as teaching carbonizing bamboo and sludge, then post-treating with a metal salt.
Wang 20180016162 page 3 is noted as teaching mixing biomass with one or more iron and other salts to make a magnetic material.
However, the prior art does not teach or suggest the claimed steps; especially the use of multiple salts in multiple steps and the pH adjustment therebetween as required by independent claim 1.
Applicant's arguments filed 3/2/26 have been fully considered but they are not persuasive.
Not all the errors were corrected.
THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
