International application No. Applicant's or agent's file reference
PCT/US2018/049190 40088-461632
International filing date (day/month/year) (Earliest) Priority Date (day/month/year)
31 August 2018 13 September 2017
Applicant
MEDTRONIC MINIMED, INC.
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:
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: 1-20
External calibration and fusion of the SG values or calibrating fused SG values based on Isig and EIS if a modification factor is valid, wherein the modification factors are physiological or environmental calibration factors. The problem to be solved can therefore be regarded as how to optimize a procedure for external calibration of glucose sensors.
2. claims: 21-35
Unconditionally calibrating Isig, EIS and Vcntr based on factory calibration statistics, followed by calculating SG values based on the factory calibrated values. The problem to be solved can therefore be regarded as how to compensate for factory dependent glucose sensor variability.
3. claims: 36-55
Optimising the sensor current offset value and the calibration factor of a relationship between current and glucose level using EIS. The problem to be solved can therefore be regarded as how to continuously adjust the calibration parameters without any additional information.
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.: 1-20
Remark on Protest
The additional search fees were accompanied by the applicant’s protest and, where applicable, the payment of a protest fee.
The additional search fees were accompanied by the applicant’s protest but the applicable protest fee was not paid within the time limit specified in the invitation.
No protest accompanied the payment of additional search fees.
4. Title of the invention
The text is approved as submitted by the applicant.
The text has been established by this Authority to read as follows:
5. Abstract
The text is approved as submitted by the applicant.
The text has been established, according to Rule 38.2, by this Authority as it appears in Box No. IV. The applicant may, within one month from the date of mailing of this international search report, submit comments to this Authority.
6. Drawings
a.
The figure of the drawings to be published with the abstract is Figure No. ____________
as suggested by the applicant.
as selected by this Authority, because the applicant failed to suggest a figure.
as selected by this Authority, because this figure better characterizes the invention.
b.
none of the figures is to be published with the abstract.
