Listed generic medicinal products have been approved for the indications covered by Xarelto®. Estonian

Agency of Medicines decides on the bases of criteria given in the Medicinal Products Act and may refuse

granting the marketing authorisation only when any of the conditions provided in § 74 of the Medicinal

Products Act exist. Medicinal Products Act § 74 does not allow to take into consideration whether importing,

marketing, offering, storing of generic rivaroxaban in Estonia is infringing existing patent rights. Therefore,

decision by the Estonian Agency of Medicines does not legitimize or exclude a patent infringement even if

the agency grants marketing authorisation for a generic rivaroxaban. Same applies to marketing

authorisations granted by the European Medicines Agency.

4.

Our client has become aware that several generic rivaroxaban marketing authorisation holders have filed a

request to the Health Insurance Fund (Tervisekassa) for the inclusion of their generic medicinal products in

the reimbursement list, including (the list is not exhaustive):

The Board of the Health Insurance Fund decides on the bases of criteria given in the Health Insurance Act §

43 (2) that does not allow to take into consideration whether importing, marketing, offering, storing of generic

rivaroxaban in Estonia is infringing existing patent rights. Therefore, decision by the Board of the Health

Insurance Fund does not legitimize or exclude a patent infringement even if the board decides to satisfy a

request to include generic rivaroxaban in the reimbursement list.

5.

According to Estonian Patents Act § 15 (1) the exclusive right of the proprietor of a patent means that during

the term of validity of the patent and without the permission of the proprietor of the patent no person shall:

• manufacture, use, distribute, sell or offer for sale products protected by the patent or acquire (incl.

by way of importation) such products for the aforesaid purposes;

• use, distribute, sell or offer for sale a product manufactured according to the patented process, or to

acquire (including by way of importation) such products for the aforesaid purposes.

Bayer has sent notice letters to all marketing authorisation holders of generic rivaroxaban in Estonia and

asked the holders to confirm that they and/or their affiliates will respect Bayer’s intellectual property rights

and will not interfere with the scope of their protection. In addition, Bayer has sent reminders to marketing

authorisation holders that have filed a request to the Health Insurance Fund for the inclusion of their generic

rivaroxaban medicinal products in the reimbursement list.

In order to protect its patent rights Bayer is preparing for a request of preliminary injunction against marketing

authorisation holders trying to enter the Estonian market with their generic rivaroxaban products that are

infringing its patent rights. Bayer will vigorously defend its patent rights including bringing preliminary

injunction requests against marketing authorisation holders trying to enter the Estonian market with generic

rivaroxaban products that infringe its patent rights. All rivaroxaban products offered or brought to the market

prior to 3 April 2024 will infringe SPC No 00025. As of 3 April 2024, every generic rivaroxaban product that is

administered once daily will also infringe EP 961, particularly rivaroxaban products with the strengths 10 mg,

6

15 mg and 20 mg. Bayer currently does not have sufficient information to determine whether also EP 866

and EP 377 are infringed by certain generic products.

Due to the above, we would like to draw your attention to the fact that buying, wholesale, offering for sale

and distributing generic rivaroxaban medicinal product in Estonia may lead to unwanted legal consequences

for the wholesalers. If you purchase, wholesale, offer for sale or distribute generic rivaroxaban medicinal

product in Estonia, you, as a wholesaler, may also become an infringer of Bayer’s patent rights.

If you infringe Bayer’s patent rights, then Bayer is entitled to use available legal remedies to protect its rights

which we would like to avoid. Therefore, we ask you to confirm by

by 23 February 2024 at the latest

that your company respects and observes the property rights of our client listed in this letter and will

not purchase, wholesale, offer for sale or otherwise distribute generic rivaroxaban medicinal

products in Estonia. Please send the corresponding confirmation by e-mail to [email protected] latest

by 21 February 2024.

Yours sincerely

Sotsiaalministeerium, e-post: [email protected] Ravimiamet, e-post: [email protected] Tervisekassa, e-post: [email protected] 05.06.2024 Tamro Eesti OÜ on Eesti Vabariigis ravimite hulgimüügiga tegelev ettevõte ja pöördume teie poole, et paluda teil kujundada omapoolne seisukoht seoses mõnede ravimitootjate poolt ravimite hulgimüüjale saadetud teavitustega ning nõudekirjadega teatud toimeainet sisaldavate ravimite müügi takistamiseks Eesti Vabariigis. Näiteks oleme saanud nõudekirja advokaadibüroolt ELLEX. Kirjas nõutakse Bayer Intellectual Property GmbH/Bayer AG nimel (esindajaks ELLEX Advokaadibüroo), et ravimite hulgimüüjad ei turustaks geneerililisi rivaroksabaan ravimeid, sh ka siis, kui neid on lubatud turustada Eesti Vabariigi ravimiameti poolt (omavad müügiluba Eestis turustamiseks) ja nende osas on sõlmitud hinnakokkulepe Tervisekassaga. Bayeri toodetav rivaroksabaani sisaldav ravim, mille kaitseks selline kiri on genereeritud, on nimega Xarelto. Advokaadibüroo kirja koopia lisatud. Ravimite hulgimüüjana peame oma kohuseks tagada apteekidele sama toimeainega ravimite kättesaadavus, mis on soodusravimite nimekirjas või mille kohta on ravikindlustuse seaduse § 45 alusel sõlmitud hinnakokkulepe. Oleme seisukohal, et ravimite hulgimüüjana on meil õigus ja kohustus pakkuda võimalusel kõiki Eesti Vabariigis kehtivat müügiluba omavaid ravimeid, sh geneerililisi rivaroksabaan ravimeid, mis on Tervisekassa soodusravimite nimekirjas ning hulgimüüja ei tohi advokaadibüroo kirja peale lõpetada geneeriliste rivaroksabaan ravimite turustamist kuni ei ole keelavat kohtulahendit Eesti kohtult. Käesolevaks hetkeks on Tamro teinud Eestis kättesaadavaks järgnevad rivaroksabaani sisaldavad geneerilised ravimid:

Käesoleval hetkel Tamrol oleva info kohaselt on ühe tootja osas 23.05.2024 tehtud ringkonnakohtu määrus, mis hagi tagamise korras keelab KRKA, d.d., Novo mesto kuni lõpliku kohtulahendi jõustumiseni, kuid mitte kauem kui 19. jaanuar 2026 ravimi XERDOXO (tablett) tugevusega 10 mg, 15 mg ja 20 mg impordi Eestisse, selle levitamise, kasutamise, müügiks pakkumise ja müümise Eestis. Käesolevaks hetkeks meile teadaolevalt teiste tootjate osas sarnast hagi tagamise määrust tehtud ei ole. Ravimiameti kodulehel avaldatud andmete kohaselt on ravimi Xarelto osas Ravimiamet keelanud selle väljaveo Eestist1. Eeldatavasti võimalike tootjapoolsete ravimi tarneraskuste tõttu. Seda enam on oluline turustada Eestis geneerililisi rivaroksabaan ravimeid, et tagada rivaroksabaan toimeainet sisaldavate geneeriliste ravimite kättesaadavus Eesti patsientidele. Kuna ravimite kättesaadavuse tagamine Eesti elanikele on meie esmane ülesanne ja arvestades eelkirjeldatut, palume teie seisukohta, kas käesolevas olukorras ravimite hulgimüüja on kohustatud tagama geneerililiste rivaroksabaan ravimite kättesaadavuse Eesti Vabariigis, st ravimid ostma ning võimaldama apteekidesse müüki, kui vastavate geneeriliste ravimite tootjad pakuvad hulgimüüjale nimetatud ravimeid ning koheselt oleks võimalik tagada nende kättesaadavus Eesti patsientidele. Hulgimüüjana peame arvestama ka asjaoluga, et näiteks ravimite 01.07.2024 hinnakokkuleppe nimekirja lisamisel ning tagamaks selle kättesaadavus Eesti patsientidele koheselt, peame ravimeid tellima juba enne 01.07.2024.

Listed generic medicinal products have been approved for the indications covered by Xarelto®. Estonian

Agency of Medicines decides on the bases of criteria given in the Medicinal Products Act and may refuse

granting the marketing authorisation only when any of the conditions provided in § 74 of the Medicinal

Products Act exist. Medicinal Products Act § 74 does not allow to take into consideration whether importing,

marketing, offering, storing of generic rivaroxaban in Estonia is infringing existing patent rights. Therefore,

decision by the Estonian Agency of Medicines does not legitimize or exclude a patent infringement even if

the agency grants marketing authorisation for a generic rivaroxaban. Same applies to marketing

authorisations granted by the European Medicines Agency.

4.

Our client has become aware that several generic rivaroxaban marketing authorisation holders have filed a

request to the Health Insurance Fund (Tervisekassa) for the inclusion of their generic medicinal products in

the reimbursement list, including (the list is not exhaustive):

The Board of the Health Insurance Fund decides on the bases of criteria given in the Health Insurance Act §

43 (2) that does not allow to take into consideration whether importing, marketing, offering, storing of generic

rivaroxaban in Estonia is infringing existing patent rights. Therefore, decision by the Board of the Health

Insurance Fund does not legitimize or exclude a patent infringement even if the board decides to satisfy a

request to include generic rivaroxaban in the reimbursement list.

5.

According to Estonian Patents Act § 15 (1) the exclusive right of the proprietor of a patent means that during

the term of validity of the patent and without the permission of the proprietor of the patent no person shall:

• manufacture, use, distribute, sell or offer for sale products protected by the patent or acquire (incl.

by way of importation) such products for the aforesaid purposes;

• use, distribute, sell or offer for sale a product manufactured according to the patented process, or to

acquire (including by way of importation) such products for the aforesaid purposes.

Bayer has sent notice letters to all marketing authorisation holders of generic rivaroxaban in Estonia and

asked the holders to confirm that they and/or their affiliates will respect Bayer’s intellectual property rights

and will not interfere with the scope of their protection. In addition, Bayer has sent reminders to marketing

authorisation holders that have filed a request to the Health Insurance Fund for the inclusion of their generic

rivaroxaban medicinal products in the reimbursement list.

In order to protect its patent rights Bayer is preparing for a request of preliminary injunction against marketing

authorisation holders trying to enter the Estonian market with their generic rivaroxaban products that are

infringing its patent rights. Bayer will vigorously defend its patent rights including bringing preliminary

injunction requests against marketing authorisation holders trying to enter the Estonian market with generic

rivaroxaban products that infringe its patent rights. All rivaroxaban products offered or brought to the market

prior to 3 April 2024 will infringe SPC No 00025. As of 3 April 2024, every generic rivaroxaban product that is

administered once daily will also infringe EP 961, particularly rivaroxaban products with the strengths 10 mg,

6

15 mg and 20 mg. Bayer currently does not have sufficient information to determine whether also EP 866

and EP 377 are infringed by certain generic products.

Due to the above, we would like to draw your attention to the fact that buying, wholesale, offering for sale

and distributing generic rivaroxaban medicinal product in Estonia may lead to unwanted legal consequences

for the wholesalers. If you purchase, wholesale, offer for sale or distribute generic rivaroxaban medicinal

product in Estonia, you, as a wholesaler, may also become an infringer of Bayer’s patent rights.

If you infringe Bayer’s patent rights, then Bayer is entitled to use available legal remedies to protect its rights

which we would like to avoid. Therefore, we ask you to confirm by

by 23 February 2024 at the latest

that your company respects and observes the property rights of our client listed in this letter and will

not purchase, wholesale, offer for sale or otherwise distribute generic rivaroxaban medicinal

products in Estonia. Please send the corresponding confirmation by e-mail to [email protected] latest

by 21 February 2024.

Yours sincerely

TAMRO EESTI OÜ Pärnu mnt 501, Laagri 76401 Harjumaa E-mail: [email protected] Tel: 650 3600

Sotsiaalministeerium, e-post: [email protected] Ravimiamet, e-post: [email protected] Tervisekassa, e-post: [email protected] 05.06.2024 Tamro Eesti OÜ on Eesti Vabariigis ravimite hulgimüügiga tegelev ettevõte ja pöördume teie poole, et paluda teil kujundada omapoolne seisukoht seoses mõnede ravimitootjate poolt ravimite hulgimüüjale saadetud teavitustega ning nõudekirjadega teatud toimeainet sisaldavate ravimite müügi takistamiseks Eesti Vabariigis. Näiteks oleme saanud nõudekirja advokaadibüroolt ELLEX. Kirjas nõutakse Bayer Intellectual Property GmbH/Bayer AG nimel (esindajaks ELLEX Advokaadibüroo), et ravimite hulgimüüjad ei turustaks geneerililisi rivaroksabaan ravimeid, sh ka siis, kui neid on lubatud turustada Eesti Vabariigi ravimiameti poolt (omavad müügiluba Eestis turustamiseks) ja nende osas on sõlmitud hinnakokkulepe Tervisekassaga. Bayeri toodetav rivaroksabaani sisaldav ravim, mille kaitseks selline kiri on genereeritud, on nimega Xarelto. Advokaadibüroo kirja koopia lisatud. Ravimite hulgimüüjana peame oma kohuseks tagada apteekidele sama toimeainega ravimite kättesaadavus, mis on soodusravimite nimekirjas või mille kohta on ravikindlustuse seaduse § 45 alusel sõlmitud hinnakokkulepe. Oleme seisukohal, et ravimite hulgimüüjana on meil õigus ja kohustus pakkuda võimalusel kõiki Eesti Vabariigis kehtivat müügiluba omavaid ravimeid, sh geneerililisi rivaroksabaan ravimeid, mis on Tervisekassa soodusravimite nimekirjas ning hulgimüüja ei tohi advokaadibüroo kirja peale lõpetada geneeriliste rivaroksabaan ravimite turustamist kuni ei ole keelavat kohtulahendit Eesti kohtult. Käesolevaks hetkeks on Tamro teinud Eestis kättesaadavaks järgnevad rivaroksabaani sisaldavad geneerilised ravimid:

Käesoleval hetkel Tamrol oleva info kohaselt on ühe tootja osas 23.05.2024 tehtud ringkonnakohtu määrus, mis hagi tagamise korras keelab KRKA, d.d., Novo mesto kuni lõpliku kohtulahendi jõustumiseni, kuid mitte kauem kui 19. jaanuar 2026 ravimi XERDOXO (tablett) tugevusega 10 mg, 15 mg ja 20 mg impordi Eestisse, selle levitamise, kasutamise, müügiks pakkumise ja müümise Eestis. Käesolevaks hetkeks meile teadaolevalt teiste tootjate osas sarnast hagi tagamise määrust tehtud ei ole. Ravimiameti kodulehel avaldatud andmete kohaselt on ravimi Xarelto osas Ravimiamet keelanud selle väljaveo Eestist1. Eeldatavasti võimalike tootjapoolsete ravimi tarneraskuste tõttu. Seda enam on oluline turustada Eestis geneerililisi rivaroksabaan ravimeid, et tagada rivaroksabaan toimeainet sisaldavate geneeriliste ravimite kättesaadavus Eesti patsientidele. Kuna ravimite kättesaadavuse tagamine Eesti elanikele on meie esmane ülesanne ja arvestades eelkirjeldatut, palume teie seisukohta, kas käesolevas olukorras ravimite hulgimüüja on kohustatud tagama geneerililiste rivaroksabaan ravimite kättesaadavuse Eesti Vabariigis, st ravimid ostma ning võimaldama apteekidesse müüki, kui vastavate geneeriliste ravimite tootjad pakuvad hulgimüüjale nimetatud ravimeid ning koheselt oleks võimalik tagada nende kättesaadavus Eesti patsientidele. Hulgimüüjana peame arvestama ka asjaoluga, et näiteks ravimite 01.07.2024 hinnakokkuleppe nimekirja lisamisel ning tagamaks selle kättesaadavus Eesti patsientidele koheselt, peame ravimeid tellima juba enne 01.07.2024.
