Office Action

§102 §112
DETAILED ACTION Specification The disclosure is fraught with indiscriminate and inconsistent description of reference characters as well as seemingly random interchanging of terms. Accordingly, the disclosure is objected to because of the following informalities: On page 13, line 18, please replace “pre-processing” with “preprocessing” so that term is consistent with spelling throughout the remainder of the specification. On page 13, line 25, please replace “block 90” with “other facility 90” so that term is consistent that recited on page 15, line 17 and 27 and on page 16, line 22. On page 18, line 27, the term “waste plastic stream 100” is inconsistent with the term “stream 100” in line 21. Please replace “waste plastic stream 100” with “stream 100 of waste plastic”.† On page 20, lines 5 and 12, please insert “100” after “total weight of the stream”. On page 20, line 11, specification introduces the term “MPW stream” which appears to be associated with reference numeral 100. However, the term “MPW stream” is inconsistent with the term “stream 100” defined on page 18, line 21. Please replace “MPW stream” with “stream 100”.† On page 20, lines 20 and 22, please insert “100” after “total weight of the stream”. ------------------------- __________________________ † Each reference numeral is associated with a single element. According to the disclosure at page 18, line 21, the stream 100 may be a stream of waste plastic, and the waste plastic may be mixed plastic waste (MPW). Therefore, the term “stream” is generic and may contain, or be a stream of, waste plastic, mixed plastic waste, or a combination of waste plastic and mixed plastic waste. The terms, “waste plastic” and “plastic waste” appear to be synonymous, but it appears that mixed plastic waste (MPW) is a type of “plastic waste”. Therefore, it is deemed that “stream 100” is neither interchangeable with, nor the same as, the terms “waste plastic stream” or “MPW stream”. On page 21, line 2, replace “the municipal waste stream (or portion of the stream)” with “stream 100”. The municipal waste constitutes a portion of stream 100, and therefore, the relative basis is stream 100, not the municipal waste stream. On page 21, lines 7, 14, 24, 28, and 31, please insert “100” after “total weight of the stream”. On page 23, lines 22 and 24, please insert “100” after “total weight of the stream”. On page 24, lines 3 and 5, please insert “100” after “total weight of the stream”. On page 24, line 12, please replace “waste plastic stream” with “stream 100 of waste plastic”; see also paragraph 3, supra. On page 24, lines 14 and 31, please insert “100” after “total weight of the stream”. On page 25, lines 2, 8, and 11, please insert “100” after “total weight of the stream”. On page 26, line 22, please insert “10” after “facility”. On page 27, line 5, please insert “10” after “facility”. On page 27, lines 15 and 17, please replace “waste plastic stream” with “stream 100 of waste plastic”. On page 30, lines 23 and 29, please insert “10” after “facility”. On page 31, line 10, please replace “MPW stream” with “stream 100”; see also paragraph 5, supra. On page 31, line 13, delete “MPW” which appears prior to “stream 100”. On page 31, line 24, the term “line 100” is inconsistent with the term “stream 100” defined on page 18, line 21. On page 32, lines 3 and 5, delete “MPW” which appears prior to “stream 100” (three occurrences). On page 35, line 17, please replace “pre-processing” with “preprocessing”. On page 35, line 25, please insert “10” after “facility”. On page 36, line 20, please insert “10” after “facility”. On page 39, line 26, please insert “10” after “facility”.

On page 74, line 15, please replace “the coproduct stream” with “the light organics solvolysis coproduct steam 152”. On page 74, line 16, please insert “solvolysis” prior to “coproduct stream 152”. On page 74, line 28, it is unclear which compound is represented by the term “EG benzoate”. On page 75, line 11, the term “stream predominantly comprising the principal glycol 154” is inconsistent with the term “stream 154 of recycle content glycol (r-glycol)” described on page 58, line 15. See also paragraph 95, supra, and Figure 3. At the very least, on line 11, insert “154” prior to “predominantly” and on line 12, delete “154” which appears prior to “may also”. In this case, reference numeral “154” corresponds generically to “stream”. On page 75, line 14, please replace “stream of principal glycol 154” with “stream 154 of principal glycol”. On page 75, line 17, please replace “principal glycol stream 154” with “stream 154 of principal glycol”. On page 75, line 18/19, please replace “principal glycol product stream 154” with “stream 154 of principal glycol”. On page 75, line 23, please replace “glycol-containing” with “glycol” so that terminology is consistent with that written in line 30 and in Figure 3. On page 78, line 6, delete “stream or” which appears after “solvolysis coproduct”. On page 78, line 6, delete “(shown as stream” and delete the close parenthesis mark “ ) ” which appears after “FIG. 1”. On page 78, line 13, please insert “110” after “streams”. On page 78, line 15, please insert “110” after streams” On page 78, line 17, please insert “solvolysis” prior to “coproduct” and insert “110” after “stream”. On page 78, line 19, please insert “solvolysis coproduct” prior to “stream” and insert “110” prior to “may be divided”. On page 78, line 22, please insert “solvolysis” prior to “coproduct” and insert “110” after “stream”. On page 78, line 26/27, please replace “PO-enriched” with “PET-depleted (or PO-enriched)”. Specification defines “PET-depleted stream 114” on page 43, line 23 and recites the term “PET-depleted (or PO-enriched) stream 114” on page 50, line 28. On page 78, line 27, delete “plastic” which appears prior to “stream 114”. On page 78, line 27, please replace “pre-processing” with “preprocessing”. On page 78, line 29, please insert “solvolysis” prior to “coproduct” and insert “110” after “streams”. On page 79, line 7, please replace “cracker” with “cracking”.

On page 79, line 11, please replace “PO-enriched” with “PET-depleted (or PO-enriched)” and delete “waste plastic”. On page 79, line 13, please insert “40” after “liquification zone”. On page 80, line 11, please insert “10” after “facility”. On page 81, lines 15 and 17, it is unclear which stream the term “total weight of the stream” refers. On page 81, line 18/19, replace “waste plastic stream” with “stream 100 of waste plastic”. See paragraph 3, supra. On page 81, lines 28 and 30, it is unclear which stream the term “total weight of the stream” refers. It cannot be stream 100, mentioned in the same paragraph because stream 100 enters a preprocessing facility 20 rather than liquification zone 40. On page 82, line 1, please replace “PO-enriched” with “PET-depleted (or PO-enriched)” and delete “plastic”. On page 82, line 2, please insert “110” after “coproduct stream”. On page 82, line 4, please replace “PO-enriched” with “PET-depleted (or PO-enriched)” and delete “waste plastic”. On page 82, line 8, please insert “110” after “coproduct streams”.

On page 82, line 29, please insert “110” after “coproduct streams”. On page 83, line 14, please insert “110” after “coproduct streams”. On page 83, line 17, please insert “161” after “plastic stream”. Based on Figure 1, it appears that specification is describing a liquified plastic stream 161 that is withdrawn from liquification zone 40. On page 83, line 27, please replace “stream” with “liquified plastic stream 161”. On page 83, line 29, please replace “stream” with “liquified plastic stream 161”.

Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. Claim 34 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. Claim recites a step of applying a recycle content value to at least a portion of a polypropylene composition. Specification at page 196, paragraph [0533] defines “recycle content value” as a unit of measure (i.e., a mass or a percentage) representative of a quantity of material having its origin in recycled waste. It is not evident how a recycle content value, or unit of measure, can be “applied to” a material, thereby converting a polypropylene composition into a recycle content polypropylene composition. That is, it is unclear what physical process is carried out resulting in a recycle content value being applied to the polypropylene composition. Claim further recites a step of deducting a recycle content value from a recycle inventory. Specification at page 196, paragraph [0534] defines a recycle inventory as an electronic or paper collection of allotments, wherein an allotment is a type recycle content value (page 194, paragraph [0524]). It is unclear from claim how such a deduction leads to one obtaining the recycle content polypropylene composition. Claim 35 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the term “same entity” in line 9. Claim 35 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the term “amount of recycle content” in line 11. Claim 35 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. Claim is drawn to a method of making a recycle content polypropylene (r-polypropylene) comprising a step b of making a polypropylene composition. None of the steps describes or indicates formation of claimed recycle content polypropylene. Therefore, claim is indefinite because it is unclear after which step(s) the r-polypropylene is actually made. Claim 35 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. Claim recites a step of applying a recycle content value to at least a portion of any polypropylene composition. Specification at page 196, paragraph [0533] defines “recycle content value” as a unit of measure (i.e., a mass or a percentage) representative of a quantity of material having its origin in recycled waste. It is not evident how a recycle content value can be “applied to” a material. That is, it is unclear what physical process is carried out when a recycle content value being applied to the polypropylene composition. Furthermore, it is entirely unclear how a recycle content value based on recycle content in dr-propylene is “applied to” a generic polypropylene composition that may or may not have any connection with the dr-propylene. Finally, it is unclear how carrying out step c) using a generic polypropylene composition, which appears to be different from the polypropylene composition in step b), results in the formation of the recycle content polypropylene (r-polypropylene). See also preceding paragraph 378. Claim 36 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the terms “r-olefin”, “r-propylene”, and “r-polypropylene”. Claim 37 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the terms “r-olefin” and “r-propylene”. Claim 38 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the terms “r-olefin” and “r-propylene”. Claim 39 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the terms “r-olefin”, “r-propylene”, and “r-polypropylene”. Claim 40 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the terms “r-olefin” and “r-propylene”. Claim 41 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the terms “r-olefin” and “r-propylene”. Claim 42 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the terms “r-olefin”, “r-propylene”, and “r-polypropylene”. Claim 43 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the terms “r-olefin” and “r-propylene”. Claim 44 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the terms “r-olefin” and “r-propylene”. Claim 45 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the term “said propylene composition” in line 1. Claim 45 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the term “said cracking” (line 2) in the context of deriving the propylene composition. Claim 45 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. Claim recites a step to obtain a r-propylene composition. Claim lacks nexus between the term “r-propylene composition” and terms “pr-propylene”, “POXr-propylene”, and “sr-propylene” recited in claim 33, and therefore, it is unclear how obtaining the r-propylene composition is related to the method of processing recited in independent claim 33. Claim 46 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the term “said pyrolysis of waste plastic” in line 2. Claim 46 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the term “said cracking of r-pyoil” in line 3. Claim 46 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. Claim lacks nexus between the term “r-propylene composition” and the term “propylene composition” in step (a) of claim 34 and the term “r-polypropylene” in step (b) of claim 34. Therefore, it is unclear how obtaining r-propylene is related to the method of making a recycle content polypropylene (r-polypropylene) recited in independent claim 34. Claim 47 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the term “said propylene composition” in line 1. Claim 47 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the term “said pyrolysis of waste plastic” in line 2. Claim 47 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the term “said cracking of r-pyoil” in line 3. Claim 47 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. Claim recites a step to obtain a r-propylene composition. Claim lacks nexus between terms “r-propylene composition” and “dr-propylene” in claim 35 and between terms “r-propylene composition” and “r-polypropylene” in claim 35. Therefore, it is unclear how obtaining the r-propylene composition is related to, or results in, formation of the recycle content polypropylene (r-polypropylene) as described in independent claim 35. Claim 50 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. There is insufficient antecedent basis for the term “said polypropylene”. The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claims 38 and 41 are rejected under 35 U.S.C. 112(d) as being indefinite for failing to particularly po
