Recently published: New empirical study of ILPO relating to pre-grant oppositions in Israel

January 22, 2017

Latest News Concept on Red Puzzle.

On January 2017, the Israeli Patents Office (“ILPO”) published the results of an empirical study relating to pre-grant opposition proceedings. The study analyzed several parameters (duration, outcome, interim proceedings, etc.) in 135 opposition files that closed in 2013-2015. The conclusions of the study, now made available to the public, provide, inter alia, insight into (a) the usefulness of pre-grant oppositions as an additional examination ‘tool’ (beyond the prosecution of patent applications) for screening ineligible patent applications; and (b) the misuse of pre-grant oppositions in Israel by third parties. The results of the study prompted the Israeli Ministry of Justice to publish a call for action relating to an overhaul of the statutory scheme of pre-grant oppositions.[1] 

Introduction

The Israeli Patents Law provides for pre-grant oppositions allowing any third party to oppose patent applications after their allowance is published by the ILPO.[2] If an opposition is filed, the patent will not be granted until the opposition is finally resolved.

As was noted in the report, that the background and rationale of the study included (a) the amendment of the Israeli Patent Law in 2012 [this amendment mainly dealt with the early publication of patent applications][3], (b) legislative changes of Israel (particularly the US and Japan), (c) a very low rate of oppositions, and (d) a general feeling that the pre-grant opposition proceedings are not efficient.

The study analyzes 135 opposition files that closed from 2013 through 2015 for the following main parameters:[4] duration of the opposition proceeding, the stage at which the opposition file was closed, outcome of the opposition and interim proceedings that were initiated during the opposition.[5] The study sought to analyze the duration and result of opposition proceedings, characteristics of parties and scientific fields  and possible factors for delays in opposition proceedings.  

The main conclusions drawn from the study, as well ours, is as follows:

I. The rate of pre-grant oppositions filed was found to be as low as 1%

The ILPO found that for those cases studied (from 2013 to 2015) about 1% of the total number of allowed patent applications were opposed.

The ILPO consequently concluded that pre-grant oppositions are actually not utilized by third parties to challenge patent applications.[6] 

We conducted further analysis of the number of oppositions filed out of the total amount of allowed applications also from 2000 through 2012 (published in the ILPO’s annual reports).[7]

The graph below represents the number of oppositions filed out of the total amount of allowed applications from 2000 through 2015:

As arises from the second below, there has been a general decrease in the rate of oppositions filed against patent applications since 2000, which can also substantiate the ILPO’s conclusion relating to the (lack of) use of oppositions by third parties over the last few years.

II. The duration of pre-grant opposition proceedings was found to be exceptionally long

The ILPO found that the duration (time lapsed from filing of the opposition until the file is closed) of those (few) oppositions litigated until a final decision in the opposition is issued[8] is around six years.

According to the data published by the ILPO, this duration is three times that of the corresponding proceeding in Europe and six times that of the corresponding proceeding in the US.

The ILPO study also shows that the average duration of all pre-grant opposition proceedings, namely, including those that are terminated before or at the pleadings stage, is around 2.5 years in cases where a motion to amend the specification was not filed and four years if a motion to amend the patent specification was filed.

The ILPO consequently concluded that the duration of oppositions in Israel is exceptionally long, particularly when compared to corresponding proceedings in Europe and in the US.

We note that since the patent is not granted in Israel until a final decision in the opposition is issued (and if an appeal is filed, until the decision in the appeal is issued), there is a very long delay in the grant of patents, which limits the patentee from enforcing its rights during this long period.

The delay resulting from the prosecution period of a patent application[9] is around five to six years.[10]

Thus, the cumulative delay in the patent’s grant could be a decade or more[11], which is more (sometimes substantially more) than half the lifetime of the patent.

Under these circumstances, the system could be abused by opponents in order to cause intentional delay in the grant of a patent.

III. The majority of the oppositions are abandoned

The main outcomes of the cases analyzed in the ILPO study are represented in the graph below.

As arises from the graph, oppositions were abandoned by the opponents in the majority of cases (61%).

In addition, only 9% of the oppositions are heard in full (until judgement by the ILPO).

The ILPO found that 85% of the oppositions that end by abandonment (the opposition or the patent application, as the case may be) end before the evidentiary stage. In addition, in about 40-50% of those proceedings, abandonment occurs even before any pleading is filed.[12]

The study shows that of those  9% of the oppositions that are heard in full, around 80% of the oppositions are accepted (in part or in full, resulting in a respective refusal of the patent application). In only one case was the opposition dismissed.

These results suggest that since a very low amount of oppositions are filed and most of these oppositions are abandoned, the usefulness of the pre-grant opposition system should be revisited, as it may not prove to be a useful tool.

IV. The fields of the patent applications for which oppositions were filed

The ILPO found that around 50% of the opposed patent applications are in the fields of pharmaceuticals, biology or chemistry, around 40% in the field of mechanics, electronics and optics and only 12% in the field of computers and communications.

We conducted further analysis of the fields of the patent applications for which oppositions were filed from 2004 through 2014 from the data published by the ILPO in the annual report for 2014.[13]  As arises from the table below, in the last decade a significant percentage of opposed  patent applications are in the field of pharma, chemistry and biology.

V. “Serial” opponents were identified

The ILPO found that oppositions in the pharma field are dominated by only two main opponents, namely, Teva (56%) and Unipharm, a local generic company (42%), which are together responsible for 98% of the oppositions in this field.

Other highly active opponents from the non-pharma industry include: Elbit Systems, IAI (Israel Aerospace Industry Ltd.), IMI (Israel Military Systems Ltd.) and Camtek.

Additional comment regarding motions for amendment of the specification (not discussed by the ILPO)

It is well worth noting that motions to amend the specification were filed in only around 30% (38 cases) of the cases studied. However, around 50% of these opposition cases were ultimately closed due to the amendment.

These results suggest that filing oppositions might not necessarily be a trigger to amendment of the patent specification; however, doing so can be found to be a useful tool to obviate the opposition proceeding in an efficient and cost-effective manner.

[12] Abandoned Oppositions: Around 54% of the abandoned oppositions were abandoned before the pleadings stage and around 32% of the oppositions at the pleadings stage (20% after filing the opponent’s statement of case and 12% after filing of the applicant’s statement of case).

Abandoned Applications: Around 43% of the abandoned patent applications were abandoned before the pleadings stage and around 42% of the patent applications at the pleadings stage (37% after filing the opponent’s statement of case and 5% after filing of the applicant’s statement of case).
