FOR FURTHER ACTION: See Form PCT/ISA/220 as well as, where applicable, item 5 below.
This international search report has been prepared by this International Searching Authority and is transmitted to the applicant according to Article 18. A copy is being transmitted to the International Bureau.
It is also accompanied by a copy of each prior art document cited in this report.
1. Basis of the report
a. With regard to the language, the international search was carried out on the basis of:
the international application in the language in which it was filed.
a translation of the international application into                                          which is the language of a translation furnished for the purposes of international search (Rules 12.3(a) and 23.1(b)).
b.
This international search report has been established taking into account the rectification of an obvious mistake authorized by or notified to this Authority under Rule 91 (Rule 43.6bis(a)).
c.
With regard to any nucleotide and/or amino acid sequence disclosed in the international application, the international search was carried out on the basis of a sequence listing filed or furnished:
2. Certain claims were found unsearchable
3. Unity of invention is lacking
This International Searching Authority found multiple inventions in this international application, as follows:
1. claims: 1-25
Process control system comprising: (a) one or more upstream processing units, each operating a flow rate; (b) a tank connected to the one or more upstream processing units; (c) a filter having an inlet, a permeate outlet and a retentate outlet connected to the tank; (d) a feed pump having an inlet connected to the tank and an outlet connected to the inlet of the filter; (e) a sensor disposed at the permeate outlet to determine a flow rate at the permeate outlet; and (f) a control system that is one of the features (i) through (iv). Process control method and process of purifying a protein.
2. claims: 26-50
Process control system comprising: a microfiltration unit; a single-pass tangential flow filter having an inlet, a permeate outlet and a retentate outlet; a feed pump with an inlet connected to the microfiltration unit and an outlet connected to the inlet of the filter; a permeate pump with an inlet connected to the permeate outlet of the filter; and a control system coupled to the permeate pump and adapted to control the permeate pump to vary a flow reduction factor, where the flow reduction factor is the ratio of feed flow to retentate flow. Process control method comprising: pumping material through a single-pass tangential flow filter having an inlet, a permeate outlet and a retentate outlet; and pumping permeate from the permeate outlet of the filter to vary a flow reduction factor, where the flow reduction factor is the ratio of feed flow to retentate flow.
1.
As all required additional search fees were timely paid by the applicant, this international search report covers all searchable claims.
2.
As all searchable claims could be searched without effort justifying additional fees, this Authority did not invite payment of additional fees.
3.
As only some of the required additional search fees were timely paid by the applicant, this international search report covers only those claims for which fees were paid, specifically claims Nos.:
4.
No required additional search fees were timely paid by the applicant. Consequently, this international search report is restricted to the invention first mentioned in the claims; it is covered by claims Nos.: 1-25
